TFS Fast Export
tfs-fast-export is a one-time tool to export source control history from TFS to Git (git-tfs, git-tf). There are several other git/tfs integration tools, but many of them only use one tfs branch, and do not include branching information or allow migration of multiple branches. tfs-fast-export instead renders the fast-import format (http://www.kernel.org/pub/software/scm/git/docs/git-fast-import.html) for use by git fast-import. This allows git to include information from multiple TFS branches as separate git branches.
Usage
Update Program.cs to use the appropriate URL and branching information. Run from the command line and pipe the data into git fast-import in a fresh git workspace. Expect errors the first time you run this. This tool has not been fully debugged or cleaned up; it worked for us to migrate once from TFS to Git. Your Mileage May Vary.
