To support your development teams upgrade from Visual Studio 2010 to Visual Studio 2012, you also upgrade from Team Foundation Server (TFS) 2010 to TFS
2012.
You need to provide a TFS 2012 test environment that:
✑ Includes data and source code from your existing TFS 2010 environment and
✑ Allows your developers to test the new TFS 2012 and Visual Studio 2012 features while keeping the current TFS 2010 environment intact.
What should you do?
