Server 2012 R2 DC Upgrade
Posted on 2014-03-18
I currently have 2 domain controllers running Server 2008 SP2 STD.
I would like to install a 3rd DC running Server 2012R2.
I have successfully prepared for this by doing the following on an existing DC...:
adprep /domainprep /gpprep
Once I run DCPROMO on the new Server 2012R2 installation I get a warning message abbout the crypto security...
Is the upgrade safe?
Anything I should be concerned about?
My goal is to demote one of the 2008 DCs and upgrade the other once this new one is in place and functioning properly.
Both my Domain and forest function level are Server 2003.
