# Import your project from Bitbucket to GitLab
Import your projects from Bitbucket to GitLab with minimal effort.
## Overview
>**Note:**
The [Bitbucket integration][bb-import] must be first enabled in order to be
able to import your projects from Bitbucket. Ask your GitLab administrator
to enable this if not already.
- At its current state, the Bitbucket importer can import:
- the repository description (GitLab 7.7+)
- the Git repository data (GitLab 7.7+)
- the issues (GitLab 7.7+)
- the issue comments (GitLab 8.15+)
- the pull requests (GitLab 8.4+)
- the pull request comments (GitLab 8.15+)
- the milestones (GitLab 8.15+)
- the wiki (GitLab 8.15+)
- References to pull requests and issues are preserved (GitLab 8.7+)
- Repository public access is retained. If a repository is private in Bitbucket
it will be created as private in GitLab as well.
## How it works
When issues/pull requests are being imported, the Bitbucket importer tries to find
the Bitbucket author/assignee in GitLab's database using the Bitbucket ID. For this
to work, the Bitbucket author/assignee should have signed in beforehand in GitLab
and **associated their Bitbucket account**. If the user is not
found in GitLab's database, the project creator (most of the times the current
user that started the import process) is set as the author, but a reference on
the issue about the original Bitbucket author is kept.
The importer will create any new namespaces (groups) if they don't exist or in
the case the namespace is taken, the repository will be imported under the user's
namespace that started the import process.
## Importing your Bitbucket repositories
1. Sign in to GitLab and go to your dashboard.
1. Click on **New project**.
![New project in GitLab](img/bitbucket_import_new_project.png)
1. Click on the "Bitbucket" button
![Bitbucket](img/import_projects_from_new_project_page.png)
1. Grant GitLab access to your Bitbucket account
![Grant access](img/bitbucket_import_grant_access.png)
1. Click on the projects that you'd like to import or **Import all projects**.
You can also select the namespace under which each project will be
imported.

# Import your project from FogBugz to GitLab
It only takes a few simple steps to import your project from FogBugz.
The importer will import all of your cases and comments with original case
numbers and timestamps. You will also have the opportunity to map FogBugz
users to GitLab users.
1. From your GitLab dashboard click 'New project'
1. Click on the 'FogBugz' button
![FogBugz](img/fogbugz_import_select_fogbogz.png)
1. Enter your FogBugz URL, email address, and password.

# Import your project from Gitea to GitLab
Import your projects from Gitea to GitLab with minimal effort.
## Overview
>**Note:**
This requires Gitea `v1.0.0` or newer.
- At its current state, Gitea importer can import:
- the repository description (GitLab 8.15+)
- the Git repository data (GitLab 8.15+)
- the issues (GitLab 8.15+)
- the pull requests (GitLab 8.15+)
- the milestones (GitLab 8.15+)
- the labels (GitLab 8.15+)
- Repository public access is retained. If a repository is private in Gitea
it will be created as private in GitLab as well.
## How it works
Since Gitea is currently not an OAuth provider, author/assignee cannot be mapped
to users in your GitLab's instance. This means that the project creator (most of
the times the current user that started the import process) is set as the author,
but a reference on the issue about the original Gitea author is kept.
The importer will create any new namespaces (groups) if they don't exist or in
the case the namespace is taken, the repository will be imported under the user's
namespace that started the import process.
## Importing your Gitea repositories
The importer page is visible when you create a new project.
![New project page on GitLab](img/import_projects_from_new_project_page.png)
Click on the **Gitea** link and the import authorization process will start.
![New Gitea project import](img/import_projects_from_gitea_new_import.png)
### Authorize access to your repositories using a personal access token
With this method, you will perform a one-off authorization with Gitea to grant
GitLab access your repositories:
1. Go to <https://you-gitea-instance/user/settings/applications> (replace
`you-gitea-instance` with the host of your Gitea instance).
1. Click **Generate New Token**.
1. Enter a token description.
1. Click **Generate Token**.
1. Copy the token hash.
1. Go back to GitLab and provide the token to the Gitea importer.
1. Hit the **List Your Gitea Repositories** button and wait while GitLab reads
your repositories' information. Once done, you'll be taken to the importer
page to select the repositories to import.
### Select which repositories to import
After you've authorized access to your Gitea repositories, you will be
redirected to the Gitea importer page.
From there, you can see the import statuses of your Gitea repositories.
- Those that are being imported will show a _started_ status,
- those already successfully imported will be green with a _done_ status,
- whereas those that are not yet imported will have an **Import** button on the
right side of the table.
If you want, you can import all your Gitea projects in one go by hitting
**Import all projects** in the upper left corner.

You can also choose a different name for the project and a different namespace,
if you have the privileges to do so.
# Import your project from GitHub to GitLab
Import your projects from GitHub to GitLab with minimal effort.
## Overview
>**Note:**
If you are an administrator you can enable the [GitHub integration][gh-import]
in your GitLab instance sitewide. This configuration is optional, users will
still be able to import their GitHub repositories with a
[personal access token][gh-token].
>**Note:**
Administrators of a GitLab instance (Community or Enterprise Edition) can also
use the [GitHub rake task][gh-rake] to import projects from GitHub without the
constrains of a Sidekiq worker.
- At its current state, GitHub importer can import:
- the repository description (GitLab 7.7+)
- the Git repository data (GitLab 7.7+)
- the issues (GitLab 7.7+)
- the pull requests (GitLab 8.4+)
- the wiki pages (GitLab 8.4+)
- the milestones (GitLab 8.7+)
- the labels (GitLab 8.7+)
- the release note descriptions (GitLab 8.12+)
- References to pull requests and issues are preserved (GitLab 8.7+)
- Repository public access is retained. If a repository is private in GitHub
it will be created as private in GitLab as well.
## How it works
When issues/pull requests are being imported, the GitHub importer tries to find
the GitHub author/assignee in GitLab's database using the GitHub ID. For this
to work, the GitHub author/assignee should have signed in beforehand in GitLab
and **associated their GitHub account**. If the user is not
found in GitLab's database, the project creator (most of the times the current
user that started the import process) is set as the author, but a reference on
the issue about the original GitHub author is kept.
The importer will create any new namespaces (groups) if they don't exist or in
the case the namespace is taken, the repository will be imported under the user's
namespace that started the import process.
## Importing your GitHub repositories
The importer page is visible when you create a new project.
![New project page on GitLab](img/import_projects_from_new_project_page.png)
Click on the **GitHub** link and the import authorization process will start.
There are two ways to authorize access to your GitHub repositories:
1. [Using the GitHub integration][gh-integration] (if it's enabled by your
GitLab administrator). This is the preferred way as it's possible to
preserve the GitHub authors/assignees. Read more in the [How it works](#how-it-works)
section.
1. [Using a personal access token][gh-token] provided by GitHub.
![Select authentication method](img/import_projects_from_github_select_auth_method.png)
### Authorize access to your repositories using the GitHub integration
If the [GitHub integration][gh-import] is enabled by your GitLab administrator,
you can use it instead of the personal access token.
1. First you may want to connect your GitHub account to GitLab in order for
the username mapping to be correct.
1. Once you connect GitHub, click the **List your GitHub repositories** button
and you will be redirected to GitHub for permission to access your projects.
1. After accepting, you'll be automatically redirected to the importer.
You can now go on and [select which repositories to import](#select-which-repositories-to-import).
### Authorize access to your repositories using a personal access token
>**Note:**
For a proper author/assignee mapping for issues and pull requests, the
[GitHub integration][gh-integration] should be used instead of the
[personal access token][gh-token]. If the GitHub integration is enabled by your
GitLab administrator, it should be the preferred method to import your repositories.
Read more in the [How it works](#how-it-works) section.
If you are not using the GitHub integration, you can still perform a one-off
authorization with GitHub to grant GitLab access your repositories:
1. Go to <https://github.com/settings/tokens/new>.
1. Enter a token description.
1. Check the `repo` scope.
1. Click **Generate token**.
1. Copy the token hash.
1. Go back to GitLab and provide the token to the GitHub importer.
1. Hit the **List Your GitHub Repositories** button and wait while GitLab reads
your repositories' information. Once done, you'll be taken to the importer
page to select the repositories to import.
### Select which repositories to import
After you've authorized access to your GitHub repositories, you will be
redirected to the GitHub importer page.
From there, you can see the import statuses of your GitHub repositories.
- Those that are being imported will show a _started_ status,
- those already successfully imported will be green with a _done_ status,

# Project importing from GitLab.com to your private GitLab instance
You can import your existing GitLab.com projects to your GitLab instance. But keep in mind that it is possible only if
GitLab support is enabled on your GitLab instance.
You can read more about GitLab support [here](http://docs.gitlab.com/ce/integration/gitlab.html)
To get to the importer page you need to go to "New project" page.
>**Note:**
If you are interested in importing Wiki and Merge Request data to your new
instance, you'll need to follow the instructions for [project export](../settings/import_export.md)
![New project page](img/gitlab_new_project_page.png)
Click on the "Import projects from GitLab.com" link and you will be redirected to GitLab.com
for permission to access your projects. After accepting, you'll be automatically redirected to the importer.
![Importer page](img/gitlab_importer.png)
To import a project, you can simple click "Import". The importer will import your repository and issues.
Once the importer is done, a new GitLab project will be created with your imported data.
# Migrating projects to a GitLab instance
1. [From Bitbucket.org](bitbucket.md)
1. [From GitHub.com of GitHub Enterprise](github.md)
1. [From GitLab.com](gitlab_com.md)
1. [From FogBugz](fogbugz.md)
1. [From Gitea](gitea.md)
1. [From SVN](svn.md)
In addition to the specific migration documentation above, you can import any
Git repository via HTTP from the New Project page. Be aware that if the
repository is too large the import can timeout.
## Migrating from self-hosted GitLab to GitLab.com
You can copy your repos by changing the remote and pushing to the new server,
but issues and merge requests can't be imported.
If you want to retain all metadata like issues and merge requests, you can use
the [import/export feature](../settings/import_export.md).
# Migrating from SVN to GitLab
Subversion (SVN) is a central version control system (VCS) while
Git is a distributed version control system. There are some major differences
between the two, for more information consult your favorite search engine.
## Overview
There are two approaches to SVN to Git migration:
1. [Git/SVN Mirror](#smooth-migration-with-a-gitsvn-mirror-using-subgit) which:
- Makes the GitLab repository to mirror the SVN project.
- Git and SVN repositories are kept in sync; you can use either one.
- Smoothens the migration process and allows to manage migration risks.
1. [Cut over migration](#cut-over-migration-with-svn2git) which:
- Translates and imports the existing data and history from SVN to Git.
- Is a fire and forget approach, good for smaller teams.
## Smooth migration with a Git/SVN mirror using SubGit
[SubGit](https://subgit.com) is a tool for a smooth, stress-free SVN to Git
migration. It creates a writable Git mirror of a local or remote Subversion
repository and that way you can use both Subversion and Git as long as you like.
It requires access to your GitLab server as it talks with the Git repositories
directly in a filesystem level.
### SubGit prerequisites
1. Install Oracle JRE 1.8 or newer. On Debian-based Linux distributions you can
follow [this article](http://www.webupd8.org/2012/09/install-oracle-java-8-in-ubuntu-via-ppa.html).
1. Download SubGit from https://subgit.com/download/.
1. Unpack the downloaded SubGit zip archive to the `/opt` directory. The `subgit`
command will be available at `/opt/subgit-VERSION/bin/subgit`.
### SubGit configuration
The first step to mirror you SVN repository in GitLab is to create a new empty
project which will be used as a mirror. For Omnibus installations the path to
the repository will be located at
`/var/opt/gitlab/git-data/repositories/USER/REPO.git` by default. For
installations from source, the default repository directory will be
`/home/git/repositories/USER/REPO.git`. For convenience, assign this path to a
variable:
```
GIT_REPO_PATH=/var/opt/gitlab/git-data/repositories/USER/REPOS.git
```
SubGit will keep this repository in sync with a remote SVN project. For
convenience, assign your remote SVN project URL to a variable:
```
SVN_PROJECT_URL=http://svn.company.com/repos/project
```
Next you need to run SubGit to set up a Git/SVN mirror. Make sure the following
`subgit` command is ran on behalf of the same user that keeps ownership of
GitLab Git repositories (by default `git`):
```
subgit configure --layout auto $SVN_PROJECT_URL $GIT_REPO_PATH
```
Adjust authors and branches mappings, if necessary. Open with your favorite
text editor:
```
edit $GIT_REPO_PATH/subgit/authors.txt
edit $GIT_REPO_PATH/subgit/config
```
For more information regarding the SubGit configuration options, refer to
[SubGit's documentation](https://subgit.com/documentation.html) website.
### Initial translation
Now that SubGit has configured the Git/SVN repos, run `subgit` to perform the
initial translation of existing SVN revisions into the Git repository:
```
subgit install $GIT_REPO_PATH
```
After the initial translation is completed, the Git repository and the SVN
project will be kept in sync by `subgit` - new Git commits will be translated to
SVN revisions and new SVN revisions will be translated to Git commits. Mirror
works transparently and does not require any special commands.
If you would prefer to perform one-time cut over migration with `subgit`, use
the `import` command instead of `install`:
```
subgit import $GIT_REPO_PATH
```
### SubGit licensing
Running SubGit in a mirror mode requires a
[registration](https://subgit.com/pricing.html). Registration is free for open
source, academic and startup projects.
We're currently working on deeper GitLab/SubGit integration. You may track our
progress at [this issue](https://gitlab.com/gitlab-org/gitlab-ee/issues/990).
### SubGit support
For any questions related to SVN to GitLab migration with SubGit, you can
contact the SubGit team directly at [support@subgit.com](mailto:support@subgit.com).
## Cut over migration with svn2git
If you are currently using an SVN repository, you can migrate the repository
to Git and GitLab. We recommend a hard cut over - run the migration command once
and then have all developers start using the new GitLab repository immediately.
Otherwise, it's hard to keep changing in sync in both directions. The conversion
process should be run on a local workstation.
Install `svn2git`. On all systems you can install as a Ruby gem if you already
have Ruby and Git installed.
```bash
sudo gem install svn2git
```
On Debian-based Linux distributions you can install the native packages:
```bash
sudo apt-get install git-core git-svn ruby
```
Optionally, prepare an authors file so `svn2git` can map SVN authors to Git authors.
If you choose not to create the authors file then commits will not be attributed
to the correct GitLab user. Some users may not consider this a big issue while
others will want to ensure they complete this step. If you choose to map authors
you will be required to map every author that is present on changes in the SVN
repository. If you don't, the conversion will fail and you will have to update
the author file accordingly. The following command will search through the
repository and output a list of authors.
```bash
svn log --quiet | grep -E "r[0-9]+ \| .+ \|" | cut -d'|' -f2 | sed 's/ //g' | sort | uniq
```
Use the output from the last command to construct the authors file.
Create a file called `authors.txt` and add one mapping per line.
```
janedoe = Jane Doe <janedoe@example.com>
johndoe = John Doe <johndoe@example.com>
```
If your SVN repository is in the standard format (trunk, branches, tags,
not nested) the conversion is simple. For a non-standard repository see
[svn2git documentation](https://github.com/nirvdrum/svn2git). The following
command will checkout the repository and do the conversion in the current
working directory. Be sure to create a new directory for each repository before
running the `svn2git` command. The conversion process will take some time.
```bash
svn2git https://svn.example.com/path/to/repo --authors /path/to/authors.txt
```
If your SVN repository requires a username and password add the
`--username <username>` and `--password <password` flags to the above command.
`svn2git` also supports excluding certain file paths, branches, tags, etc. See
[svn2git documentation](https://github.com/nirvdrum/svn2git) or run
`svn2git --help` for full documentation on all of the available options.
Create a new GitLab project, where you will eventually push your converted code.
Copy the SSH or HTTP(S) repository URL from the project page. Add the GitLab
repository as a Git remote and push all the changes. This will push all commits,
branches and tags.
```bash
git remote add origin git@gitlab.com:<group>/<project>.git
git push --all origin
git push --tags origin
```

### Authorize access to your repositories using a personal access token
With this method, you will perform a one-off authorization with Gitea to grant
GitLab access your repositories:
1. Go to <https://you-gitea-instance/user/settings/applications> (replace
`you-gitea-instance` with the host of your Gitea instance).
1. Click **Generate New Token**.
1. Enter a token description.
1. Click **Generate Token**.
1. Copy the token hash.
1. Go back to GitLab and provide the token to the Gitea importer.
1. Hit the **List Your Gitea Repositories** button and wait while GitLab reads
your repositories' information. Once done, you'll be taken to the importer
page to select the repositories to import.
### Select which repositories to import
After you've authorized access to your Gitea repositories, you will be
redirected to the Gitea importer page.
From there, you can see the import statuses of your Gitea repositories.
- Those that are being imported will show a _started_ status,
- those already successfully imported will be green with a _done_ status,
- whereas those that are not yet imported will have an **Import** button on the
right side of the table.
If you want, you can import all your Gitea projects in one go by hitting
**Import all projects** in the upper left corner.

You can also choose a different name for the project and a different namespace,
if you have the privileges to do so.
# Import your project from GitHub to GitLab This document was moved to a [new location](../../user/project/import/github.md).
Import your projects from GitHub to GitLab with minimal effort.
## Overview
>**Note:**
If you are an administrator you can enable the [GitHub integration][gh-import]
in your GitLab instance sitewide. This configuration is optional, users will
still be able to import their GitHub repositories with a
[personal access token][gh-token].
>**Note:**
Administrators of a GitLab instance (Community or Enterprise Edition) can also
use the [GitHub rake task][gh-rake] to import projects from GitHub without the
constrains of a Sidekiq worker.
- At its current state, GitHub importer can import:
- the repository description (GitLab 7.7+)
- the Git repository data (GitLab 7.7+)
- the issues (GitLab 7.7+)
- the pull requests (GitLab 8.4+)
- the wiki pages (GitLab 8.4+)
- the milestones (GitLab 8.7+)
- the labels (GitLab 8.7+)
- the release note descriptions (GitLab 8.12+)
- References to pull requests and issues are preserved (GitLab 8.7+)
- Repository public access is retained. If a repository is private in GitHub
it will be created as private in GitLab as well.
## How it works
When issues/pull requests are being imported, the GitHub importer tries to find
the GitHub author/assignee in GitLab's database using the GitHub ID. For this
to work, the GitHub author/assignee should have signed in beforehand in GitLab
and **associated their GitHub account**. If the user is not
found in GitLab's database, the project creator (most of the times the current
user that started the import process) is set as the author, but a reference on
the issue about the original GitHub author is kept.
The importer will create any new namespaces (groups) if they don't exist or in
the case the namespace is taken, the repository will be imported under the user's
namespace that started the import process.
## Importing your GitHub repositories
The importer page is visible when you create a new project.
![New project page on GitLab](img/import_projects_from_new_project_page.png)
Click on the **GitHub** link and the import authorization process will start.
There are two ways to authorize access to your GitHub repositories:
1. [Using the GitHub integration][gh-integration] (if it's enabled by your
GitLab administrator). This is the preferred way as it's possible to
preserve the GitHub authors/assignees. Read more in the [How it works](#how-it-works)
section.
1. [Using a personal access token][gh-token] provided by GitHub.
![Select authentication method](img/import_projects_from_github_select_auth_method.png)
### Authorize access to your repositories using the GitHub integration
If the [GitHub integration][gh-import] is enabled by your GitLab administrator,
you can use it instead of the personal access token.
1. First you may want to connect your GitHub account to GitLab in order for
the username mapping to be correct.
1. Once you connect GitHub, click the **List your GitHub repositories** button
and you will be redirected to GitHub for permission to access your projects.
1. After accepting, you'll be automatically redirected to the importer.
You can now go on and [select which repositories to import](#select-which-repositories-to-import).
### Authorize access to your repositories using a personal access token
>**Note:**
For a proper author/assignee mapping for issues and pull requests, the
[GitHub integration][gh-integration] should be used instead of the
[personal access token][gh-token]. If the GitHub integration is enabled by your
GitLab administrator, it should be the preferred method to import your repositories.
Read more in the [How it works](#how-it-works) section.
If you are not using the GitHub integration, you can still perform a one-off
authorization with GitHub to grant GitLab access your repositories:
1. Go to <https://github.com/settings/tokens/new>.
1. Enter a token description.
1. Check the `repo` scope.
1. Click **Generate token**.
1. Copy the token hash.
1. Go back to GitLab and provide the token to the GitHub importer.
1. Hit the **List Your GitHub Repositories** button and wait while GitLab reads
your repositories' information. Once done, you'll be taken to the importer
page to select the repositories to import.
### Select which repositories to import

# Project importing from GitLab.com to your private GitLab instance This document was moved to a [new location](../../user/project/import/gitlab_com.md).
You can import your existing GitLab.com projects to your GitLab instance. But keep in mind that it is possible only if
GitLab support is enabled on your GitLab instance.
You can read more about GitLab support [here](http://docs.gitlab.com/ce/integration/gitlab.html)
To get to the importer page you need to go to "New project" page.
>**Note:**
If you are interested in importing Wiki and Merge Request data to your new instance, you'll need to follow the instructions for [project export](../../user/project/settings/import_export.md)
![New project page](gitlab_importer/new_project_page.png)
Click on the "Import projects from GitLab.com" link and you will be redirected to GitLab.com
for permission to access your projects. After accepting, you'll be automatically redirected to the importer.
![Importer page](gitlab_importer/importer.png)
To import a project, you can simple click "Import". The importer will import your repository and issues.
Once the importer is done, a new GitLab project will be created with your imported data.

# Migrating from SVN to GitLab This document was moved to a [new location](../../user/project/import/svn.md).
Subversion (SVN) is a central version control system (VCS) while
Git is a distributed version control system. There are some major differences
between the two, for more information consult your favorite search engine.
## Overview
There are two approaches to SVN to Git migration:
1. [Git/SVN Mirror](#smooth-migration-with-a-gitsvn-mirror-using-subgit) which:
- Makes the GitLab repository to mirror the SVN project.
- Git and SVN repositories are kept in sync; you can use either one.
- Smoothens the migration process and allows to manage migration risks.
1. [Cut over migration](#cut-over-migration-with-svn2git) which:
- Translates and imports the existing data and history from SVN to Git.
- Is a fire and forget approach, good for smaller teams.
## Smooth migration with a Git/SVN mirror using SubGit
[SubGit](https://subgit.com) is a tool for a smooth, stress-free SVN to Git
migration. It creates a writable Git mirror of a local or remote Subversion
repository and that way you can use both Subversion and Git as long as you like.
It requires access to your GitLab server as it talks with the Git repositories
directly in a filesystem level.
### SubGit prerequisites
1. Install Oracle JRE 1.8 or newer. On Debian-based Linux distributions you can
follow [this article](http://www.webupd8.org/2012/09/install-oracle-java-8-in-ubuntu-via-ppa.html).
1. Download SubGit from https://subgit.com/download/.
1. Unpack the downloaded SubGit zip archive to the `/opt` directory. The `subgit`
command will be available at `/opt/subgit-VERSION/bin/subgit`.
### SubGit configuration
The first step to mirror you SVN repository in GitLab is to create a new empty
project which will be used as a mirror. For Omnibus installations the path to
the repository will be located at
`/var/opt/gitlab/git-data/repositories/USER/REPO.git` by default. For
installations from source, the default repository directory will be
`/home/git/repositories/USER/REPO.git`. For convenience, assign this path to a
variable:
```
GIT_REPO_PATH=/var/opt/gitlab/git-data/repositories/USER/REPOS.git
```
SubGit will keep this repository in sync with a remote SVN project. For
convenience, assign your remote SVN project URL to a variable:
```
SVN_PROJECT_URL=http://svn.company.com/repos/project
```
Next you need to run SubGit to set up a Git/SVN mirror. Make sure the following
`subgit` command is ran on behalf of the same user that keeps ownership of
GitLab Git repositories (by default `git`):
```
subgit configure --layout auto $SVN_PROJECT_URL $GIT_REPO_PATH
```
Adjust authors and branches mappings, if necessary. Open with your favorite
text editor:
```
edit $GIT_REPO_PATH/subgit/authors.txt
edit $GIT_REPO_PATH/subgit/config
```
For more information regarding the SubGit configuration options, refer to
[SubGit's documentation](https://subgit.com/documentation.html) website.
### Initial translation
Now that SubGit has configured the Git/SVN repos, run `subgit` to perform the
initial translation of existing SVN revisions into the Git repository:
```
subgit install $GIT_REPO_PATH
```
After the initial translation is completed, the Git repository and the SVN
project will be kept in sync by `subgit` - new Git commits will be translated to
SVN revisions and new SVN revisions will be translated to Git commits. Mirror
works transparently and does not require any special commands.
If you would prefer to perform one-time cut over migration with `subgit`, use
the `import` command instead of `install`:
```
subgit import $GIT_REPO_PATH
```
### SubGit licensing
Running SubGit in a mirror mode requires a
[registration](https://subgit.com/pricing.html). Registration is free for open
source, academic and startup projects.
We're currently working on deeper GitLab/SubGit integration. You may track our
progress at [this issue](https://gitlab.com/gitlab-org/gitlab-ee/issues/990).
### SubGit support
For any questions related to SVN to GitLab migration with SubGit, you can
contact the SubGit team directly at [support@subgit.com](mailto:support@subgit.com).
## Cut over migration with svn2git
If you are currently using an SVN repository, you can migrate the repository
to Git and GitLab. We recommend a hard cut over - run the migration command once
and then have all developers start using the new GitLab repository immediately.
Otherwise, it's hard to keep changing in sync in both directions. The conversion
process should be run on a local workstation.
Install `svn2git`. On all systems you can install as a Ruby gem if you already
have Ruby and Git installed.
```bash
sudo gem install svn2git
```
On Debian-based Linux distributions you can install the native packages:
```bash
sudo apt-get install git-core git-svn ruby
```
Optionally, prepare an authors file so `svn2git` can map SVN authors to Git authors.
If you choose not to create the authors file then commits will not be attributed
to the correct GitLab user. Some users may not consider this a big issue while
others will want to ensure they complete this step. If you choose to map authors
you will be required to map every author that is present on changes in the SVN
repository. If you don't, the conversion will fail and you will have to update
the author file accordingly. The following command will search through the
repository and output a list of authors.
```bash
svn log --quiet | grep -E "r[0-9]+ \| .+ \|" | cut -d'|' -f2 | sed 's/ //g' | sort | uniq
```
Use the output from the last command to construct the authors file.
Create a file called `authors.txt` and add one mapping per line.
```
janedoe = Jane Doe <janedoe@example.com>
johndoe = John Doe <johndoe@example.com>
```
If your SVN repository is in the standard format (trunk, branches, tags,
not nested) the conversion is simple. For a non-standard repository see
[svn2git documentation](https://github.com/nirvdrum/svn2git). The following
command will checkout the repository and do the conversion in the current
working directory. Be sure to create a new directory for each repository before
running the `svn2git` command. The conversion process will take some time.
```bash
svn2git https://svn.example.com/path/to/repo --authors /path/to/authors.txt
```
If your SVN repository requires a username and password add the
`--username <username>` and `--password <password` flags to the above command.
`svn2git` also supports excluding certain file paths, branches, tags, etc. See
[svn2git documentation](https://github.com/nirvdrum/svn2git) or run
`svn2git --help` for full documentation on all of the available options.
Create a new GitLab project, where you will eventually push your converted code.
Copy the SSH or HTTP(S) repository URL from the project page. Add the GitLab
repository as a Git remote and push all the changes. This will push all commits,
branches and tags.
```bash
git remote add origin git@gitlab.com:<group>/<project>.git
git push --all origin
git push --tags origin
```
