Ok, I have a virtual Windows 2003 DC on a Windows 2008 R2 server. I need to rebuild the server with Windows 2012 R2 that I have on my other hyper-v servers.
I have 2 DC's on this site but this DC is the primary. So I either backup with Veeam and restore it on the other Hyper-V server (Windwos 2012 R2), or just shut it down, rebuild the server and restore the Veeam DC backup. I dont want to do a upgrade as would prefer a clean install.
