For the moment we use Conchango's Scrum template v2.1.  We have some older TFS Team Projects created with an older version of the template, which isn't availlable anymore on the server.  Now we want to know in what version these team projects are created. 

You can get the info with a certain report, namely the version report.

This report will give you the report version and depending on the version info about the process time.  As you can see in the next picture.

The report version is the same as the Template version.
