Upgrading Windows Server 2012 Standard as Domain Controller to Datacenter

I mistakenly installed Windows Server 2012 Standard Edition in a virtual machine.  A contractor arrived and promoted it to be the new domain controller.  All was well until the next day I attempted to activate Windows and realized it was the wrong version (we have a volume license).  The previous domain controller is still online, but the new one is the primary.  There is also another server that is the backup domain controller.

How can I upgrade the new domain controller from 2012 Standard to 2012 Datacenter?  I know I can upgrade Standard to Datacenter if not a DC using powershell.  Can I demote the DC, upgrade it, and promote it back to a DC?  Would that work?  Thanks.  Oh.  All servers are on the same subnet.  The DC is also running our DNS and DHCP services.

Dear,
please confirm your fsmo holder ( netdom query / fsmo)
Transfer fsmo roles to another dc.
wait for at least 1 or 2 days.
demote current dc to a server.  Install desired windows and promote to dc.

The key for me in getting this resolved was the confirmation of which DC held the FSMO roles.  Using the netdom query fsmo did the trick as I found that the Schema Master role was not where I thought it was.  I was able to transfer that role to the desired DC and then I was able to transfer the other roles to the same desired DC.  Now I can upgrade the 2012 Std server after demoting it.  Thanks Syed.
