I recently migrated a .NET 3.5 project to .NET 4 and now want to add the converted project to a TFS 10 server while keeping the original intact on a TFS 08 server because we also need to maintain the current 3.5 project since some customers still use it.
I'm having a problem disconnecting the solution's source control the TFS 08 so that I can add it to TFS 10. I've tried several ways, including some suggested here, without success. VS 10 doesn't allow me to switch servers while selecting a different location in the process of adding it to source control. I've also tried removing all mapping because it somehow still knows where the solution comes from. I even tried following "How to permanently remove TFS Source Control association bindings?" at http://zayko.net/post/How-to-permanently-remove-TFS-Source-Control-association-bindings.aspx and the son-of-gunner still knows.
