Rename tfs.md to tfvc.md and update

the tfs.md doc was actually about tfvc, so it was renamed
and content made more up to date, with light copy edits

-# Migrating from TFS
+---
+redirect_to: 'tfvc.md'

-[TFS](https://azure.microsoft.com/en-us/services/devops/server/) is a set of tools developed by Microsoft
-which also includes a centralized version control system (TFVC) similar to Git.
-
-In this document, we emphasize on the TFVC to Git migration.
-
-## TFVC vs Git
-
-The following list illustrates the main differences between TFVC and Git:
-
-- **Git is distributed** whereas TFVC is centralized using a client-server
-  architecture. This translates to Git having a more flexible workflow since
-  your working area is a copy of the entire repository. This decreases the
-  overhead when switching branches or merging for example, since you don't have
-  to communicate with a remote server.
-- **Storage method.** Changes in CVS are per file (changeset), while in Git
-  a committed file(s) is stored in its entirety (snapshot). That means that's
-  very easy in Git to revert or undo a whole change.
-
-Check also Microsoft's documentation on the
-[comparison of Git and TFVC](https://docs.microsoft.com/en-us/azure/devops/repos/tfvc/comparison-git-tfvc?view=azure-devops)
-and the Wikipedia
-[comparison of version control software](https://en.wikipedia.org/wiki/Comparison_of_version_control_software).
-
-## Why migrate
-
-Migrating to Git/GitLab there is:
-
-- **No licensing costs**, Git is GPL while TFVC is proprietary.
-- **Shorter learning curve**, Git has a big community and a vast number of
-  tutorials to get you started (see our [Git topic](../../../topics/git/index.md)).
-- **Integration with modern tools**, migrating to Git and GitLab you can have
-  an open source end-to-end software development platform with built-in version
-  control, issue tracking, code review, CI/CD, and more.
-
-## How to migrate
-
-The best option to migrate from TFVC to Git is to use the
-[`git-tfs`](https://github.com/git-tfs/git-tfs) tool. A specific guide for the
-migration exists:
-[Migrate TFS to Git](https://github.com/git-tfs/git-tfs/blob/master/doc/usecases/migrate_tfs_to_git.md).

+# Migrating from TFVC to Git
+
+Team Foundation Server (TFS), renamed [Azure DevOps Server](https://azure.microsoft.com/en-us/services/devops/server/)
+in 2019, is a set of tools developed by Microsoft which also includes
+[Team Foundation Version Control](https://docs.microsoft.com/en-us/azure/devops/repos/tfvc/overview)
+(TFVC), a centralized version control system similar to Git.
+
+In this document, we focus on the TFVC to Git migration.
+
+## TFVC vs Git
+
+The main differences between TFVC and Git are:
+
+- **Git is distributed:** While TFVC is centralized using a client-server architecture,
+  Git is distributed. This translates to Git having a more flexible workflow since
+  you work with a copy of the entire repository. This allows you to quickly
+  switch branches or merge, for example, without needing to communicate with a remote server.
+- **Storage:** Changes in a centralized version control system are per file (changeset),
+  while in Git a committed file is stored in its entirety (snapshot). That means that it is
+  very easy to revert or undo a whole change in Git.
+
+For more information, see:
+
+- Microsoft's [comparison of Git and TFVC](https://docs.microsoft.com/en-us/azure/devops/repos/tfvc/comparison-git-tfvc?view=azure-devops).
+- The Wikipedia [comparison of version control software](https://en.wikipedia.org/wiki/Comparison_of_version_control_software).
+
+## Why migrate
+
+Advantages of migrating to Git/GitLab:
+
+- **No licensing costs:** Git is open source, while TFVC is proprietary.
+- **Shorter learning curve:** Git has a big community and a vast number of
+  tutorials to get you started (see our [Git topic](../../../topics/git/index.md)).
+- **Integration with modern tools:** After migrating to Git and GitLab, you will have
+  an open source, end-to-end software development platform with built-in version
+  control, issue tracking, code review, CI/CD, and more.
