I currently have an SBS 2003 AD environment that I am trying to add a 2012 R2 Server (Hyper V Guest) and promote as a DC. I will be removing the SBS 2003 server after I get the new DC up and running to re-commission it.
I have raised the Forest/Domain functional levels to 2003 native mode and I have extended the schema to 2003 R2 using the hotfix KB919151.
Schema Version 30 = 2003
Schema Version 31 = 2003 R2
I have confirmed that we are at version: 31

However, when I try to promote the 2012 R2 server to DC if fails.
The Error:
Verification of replica failed. The forest functional level is Windows 2000. To install a windows server 2012 R2 domain controller the forest functional level must be 2003 or higher.
Event Log:
6012 DFSR DFS Replication
The DFS Replication service detected an incompatible AD schema version while trying to read objects from the server. The service disconnected from this server and will try again in the next polling cycle.
Additional information:
Expected Version: 31
Incompatible Server Version: 30

I have used ADSIEDIT to verify that my AD Schema Version is at:  31
I can ping DC and resolve DC by name without issue.

Other info:
We recently took our email to the cloud and so I have removed Exchange 2003 off of this server.

Has anyone run into this issue and know how to get around it??

To confirm, you are not using dcpromo, correct?  The method changed in 2012.
