TFS2010/SQL Server 2008 R2 standalone hardware has crashed. I have the windows backups for the machine.
Can I migrate these databases directly to a new TFS2012/SQL Server 2012 setup?
This would save time but I would like some opinions from anyone that has attempted this forced upgrade. I have read a number of blogs from other efforts but have not found this specific route. My main concern is the validity of the "Tfs..." databases when I try to attach them to the new SQL Server.
Yes you can.
However I would recommend that you install the latest version of TFS which is TFS 2017 Update 1. There is no value in maintaining old software infrastructure when it is free to upgrade. Since you are on TFS 2010 you should go to TFS 2013.5 first... Then to 2017.
