I'm moving teamcity V9.0.3 installed on a Win 2008, to V10.0.1 on Win 2012. The V9 agents are on the same Win2008 box.
I need to keep the V9 environment fully intact (but off) until I have confirmed the V10 environment fully work when I will cut over to it.I am going to use the backup/restore path. However I note the restore option only offers only 2 options: backup to new external or internal database. Does this mean the restore process re-writes the database, & practically I will need a new database instance for the V10.
