Thanks for the link, it led to something that I really needed to know and was absolutely helpful. 
That led to this in their step 6: 
<a href="http://community.spiceworks.com/how_to/show/57636-migrate-active-directory-from-server-2003-to-server-2012-r2" rel="ugc">FSMO Roles Transfer before DCPROMO to demote or remove 2003 or other DC</a>
</div>

Followed the guide in the above posting. &nbsp;It worked great. &nbsp;At the step where you run DCPROMO on the old Windows 2003 DC it can't find any other controllers. &nbsp;This despite having transferred all FSMO roles to the new DC Windows Server 2012. &nbsp; When I run dcdiag /q &nbsp;I get the following up put. &nbsp;help?

We need some help figuring out what DCPROMO will do when we run it. 
We have a new server Windows 2012 that has been properly joined to the DOMAIN.

DCPROMO Server 2003

The Microsoft Legacy Operating System topic includes legacy versions of Microsoft operating systems prior to Windows 2000: All versions of MS-DOS and other versions developed for specific manufacturers and Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions, and Windows Mobile.

Microsoft Legacy OS

The Microsoft Server topic includes all of the legacy versions of the operating system, including the Windows NT 3.1, NT 3.5, NT 4.0 and Windows 2000 and Windows Home Server versions.

Microsoft Server OS

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
