[Update: The sources for VSSConverterGui are now available on CodePlex: http://www.codeplex.com/Wiki/View.aspx?ProjectName=VssConverterGui ]
If you’re going to migrate your SourceSafe repository to Team System, you’ll eventually meet VSSConverter. VSSConverter is a command line utility that uses xml configuration files to transfer SourceSafe projects to TFS. If you don’t like command line utilities then you’ve come to the right place. I’ve written a GUI frontend to VSSConverter that is called..well.. VSSConverterGui .
To use the tool, you should get familiar with the VSSConverter docs. I also suggest reading the following: Step by Step: Migration process from VSS to Team Foundation.
If you found this useful or (more likely) found some bugs, drop me a line in the comments section.
Note: Extract and place in the same location as VssConverter.exe
[Update: Added the features requested by Dave Novak (items 1 & 2). Fixed the bugs found by Doug Rohrer. Thanks guys!]
