Windows Server 2012 Active Directory removal for license key

We have two virtual domain controllers running Windows server 2012 Eval edition. Both have active directory and replication to each other. We need to add the license key to both machines, but according to Microsoft, AD can't be present when the code is added to change the version from eval mode. Are there any issues to be aware of when removing AD for the license key addition and then putting it back on? We will still have one AD server running while the other is not, and then vice versa.

Scroll down to convert eval to full.

Yes, thats the page that says...

"If the server is a domain controller, you cannot convert it to a retail version. In this case, install an additional domain controller on a server that runs a retail version and remove AD DS from the domain controller that runs on the evaluation version"

So our concern is what could be the pitfalls to temporarily removing AD to convert the edition from eval to paid? Removing AD and adding it back sounds a bit scary? Will there be repercussions? What could happen to NTFS shares on this server?

If this is your PDC

promote the other DC and move the roles
demote the DC and remove AD
Upgrade the server
Add it back and promote the server
move the roles back

Or since they are virtual you would just create a windows server 2012, promote it and move all the data over to it and make that one your primary then just decommission the old ones.

Presuming the hypervisor isn't an eval version - can you create a new VM, register it and promote it to a DC?

Leave it for a few days/week and transfer the FSMO roles as NRhode mentioned.

Demote one of the other DC's, register and then re-register if you wish.....although if you are on Hyper-V 2012 you may want to just look at DC Cloning once you've registered the first DC and just decommission and delete the 2 evals (I usually delete the instance a while after they've been turned off just to make sure everything is OK).
