Is there a simple way to upgrade from Win Server 2012 Datacenter to 2012 R2 in a VM? One can create a new VM in the portal with R2, but there doesn't appear to be a way to upgrade an existing VM. I could back up the data, delete the current VM, create a new one with R2, and restore my data. But is there a better way that preserves data and my current DNS name?
Thanks in advance!
