I have currently Unity UM version 4.05 and want to upgrade server and upgrade Unity to version 5. My plan is to extend schema (Unity version 5),upgrade current production version to 5, install latest DiRT, and run a backup. Next, install new server into domain using a new server name, install Unity version 5, integrate with Exchange (2003), take production box off network, and then do a DiRT restore on new server.
Does anyone see a flaw in this process? Thanks!
