For a long time, we have had no home for questions related to migration offerings such as the VSS Converter, as well as general questions about our tools, partners, and service offerings. We’ve recently added a new forum on MSDN to serve as the home for questions related to all of these things: Team Foundation Server - Migration and Integration
With the recent release of the TFS Integration Platform, we’re also leveraging this forum as the discussion forum for the platform and the CodePlex project. This will help to drive all of the questions and discussions for the entire TFS migration space to a single location.
Something this forum is not intended to support are questions related to upgrading between TFS versions. For those questions, the TFS General (http://social.msdn.microsoft.com/Forums/en-US/tfsgeneral/threads) or TFS Setup (http://social.msdn.microsoft.com/Forums/en-US/tfssetup/threads) forums are your best bets.
