Problems with old SfTS-Templates and Sharepoint

Aug 6, 2013 at 4:25 PM
Just now we are using TFS 2010 with SfTS-Tempölates version 3. In this TFS we've also older projects with templates of version 2. Now we'd like to migrate to TFS 2012. We are willing to start with neew projects with the original Microsoft templates. But we also want to bring our old projects back into the new TFS. It's not possible for us to get access to our old documents. We always get error 404. Does anyone have any hints?
