I need to upgrade from Windows Server 2012 Essential Eval version to Windows Server 2012 R2 Retail. What would be the easiest way to upgrade if license $$ is not an issue? The Server is a DC. Would the following works:
1. Upgrade from Windows Server 2012 Essential Eval to Windows Server 2012 Essential Retail
2. Do a conversion from Windows Server 2012 Essential Retail to Windows Server 2012 Standard Retail (I suppose this just require several command line to enable the 2012 Standard)
3. Do an in-place upgrade from Windows Server 2012 Standard to Windows Server 2012 R2 Standard (there is no need to do migration, am I right?)
Thanks.
