Finally moving away from Windows 2003 domain to Windows 2008. I ave two 2008 r2 DCs and one remaining 2003 SP2 DC. The '03 server is still the Ops master. When I try to move the Ops master to the desired '08 server it is not avail via the GUID.
The '03 server is not a DNS server. Both new DCs in '08 are DNS servers.
What step am I missing to move the Ops master from this '03 server?
Note: Site has another server running Exchange 2003 SP2 on another server. This will be transitioned to Exchange 2010 in the next 2 weeks.
