Our integration team at work has a number of project files stored in VSS 2005, and would like to move to Team Foundation Server 2008. The development IDEs are a mix of Visual Studio 2005, Visual Studio 2003, Cast Iron, MSSQL 2005 SSIS packages, etc. Is there any way to migrate without the learning curve of VS2008? So that we can move the source control mechanism to TFS? Any help appreciated!
