Single domain AD forest.
I’ve successfully build new Win2012 R2 server (NEWDC01) as Domain Controller (PDC, RID pool manager, Infrastructure master roles) which also run as the primary DNS server.
I’m in the process of decommissioning the Win2003 server (OLDDC01) as the domain controller and the DNS server for my head office.
I’ve already configured the DHCP scope in the old Windows Server 2003 (OLDDC01) Scope Options 004 to point to the PDC role (NEWDC01)
I’ve verified that the DHCP scope options for the DNS server has been updated to the new DNS server on NEWDC01.
All domain joined servers is now pointing to the domain controllers in the Data Center AD site which each of them is pointing to the PDC Emulator role in the Head Office AD site.
