# From 6.4 to 6.5

### 0. Backup

```bash
cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
```

### 1. Stop server

    sudo service gitlab stop

### 2. Get latest code

```bash
cd /home/git/gitlab
sudo -u git -H git fetch --all
sudo -u git -H git checkout 6-5-stable
# For GitLab Enterprise Edition: sudo -u git -H git checkout 6-5-stable-ee
```

### 3. Update gitlab-shell (and its config)

```bash
cd /home/git/gitlab-shell
sudo -u git -H git fetch
sudo -u git -H git checkout v1.8.0
```

### 4. Install libs, migrations, etc.

```bash
cd /home/git/gitlab

# MySQL
sudo -u git -H bundle install --without development test postgres --deployment

# PostgreSQL
sudo -u git -H bundle install --without development test mysql --deployment


# Run database migrations
sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production

# Clean up assets and cache
sudo -u git -H bundle exec rake assets:clean assets:precompile cache:clear RAILS_ENV=production

# Update init.d script
sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
```

### 5. Start application

    sudo service gitlab start
    sudo service nginx restart

### 8. Check application status

Check if GitLab and its environment are configured correctly:

    sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production

To make sure you didn't miss anything run a more thorough check with:

    sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production

If all items are green, then congratulations upgrade complete!

## Things went south? Revert to previous version (6.4)

### 1. Revert the code to the previous version
Follow the [`upgrade guide from 6.3 to 6.4`](6.3-to-6.4.md), except for the database migration 
(The backup is already migrated to the previous version)

### 2. Restore from the backup:

```bash
cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production
```
