Enterprise Developer supports the Visual Studio Project Round-Tripping feature (or Backward Compatibility for projects) with COBOL projects. Project Round-Tripping was first introduced in Visual Studio 2010 Service Pack 1 (SP1).

Project round-tripping enables you to open and change a project in one of the Visual Studio versions and, after closing it, open and edit it in the other version - no upgrade will be applied.
