We have just upgraded from TFS 2010 to TFS 2015 Update 3, migrating onto a new server.
After updating the settings in TeamCity with a new VCR Root and TFS URL, the build fails with the following:
10:36:33] [Updating sources] Will perform clean checkout. Reason: Checkout directory is empty or doesn't exist

I tried using the TF command in C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE to create a workspace of the same name, for the same user and owner, and it produced an error, saying the workspace was remote, and it should be a local workspace.
It is not possible to create a local workspace with the above command, so how on earth did TeamCity build on the previous server? I see no evidence of any workspaces with the above names, apart from in the settings files, in the cache folder, for the build agent(s).
It's not an option to perform further upgrades just yet.
Can anyone help?
