Apologies if this is not in the proper forum; this is the closest that I could find.

I am attempting to test an upgrade of our TFS 2013 installation to TFS 2018. Everything that I have seen online shows that this is possible.

Our current TFS instance is 2013 (v12.0.30324.0) running on a Win 2008 server. It connects to a database on another server (win 2012/sql 2012).

We set up a Win 2016 server for the new front-end, which is connecting to SQL server 2016 (currently latest build, 2016 sp2: 13.0.5292.0). The database has been successfully backed up from the existing instance and restored to the new 2016 sql instance.

I start the TFS installation process, select that I will be doing an upgrade, and when it asks to specify a Team Foundation Server configuration database, I enter the server name and get this error: "No Team Foundation Server databases were found on the given SQL Server Instance."

I can manually connect to the database through SSMS.

I can’t find any references to this on the web – everything talks about migrating from one instance to another instance of TFS, where an error regarding detaching a database occurs, but this doesn’t even recognize the database.

Any ideas what the issue might be?
