I am in the processing of migrating TFS (2010 -> 2015) to a new server (Windows Server 2008 r2 -> 2012). I moved 3 collections (2 test and 1 inactive) over to the new server and can see them all in Team Foundation Server Administration Console
on the server. Every collection shows the expected team projects. In VS 2010, I successfully added the new Team Foundation Server. However, one of the collections I added does not appear in the list of Team Project Collections. I used
the exact same process when migrating the collections and I don't see any obvious differences in the settings between collections. The next step I need to take is to migrate the active collections to the new server, but am nervous that the same problem
could occur with these collections.
Any help would be greatly appreciated.
