Can anyone here please share the steps and the caveats when promoting Windows Server 2012 R2 as domain controller in my existing Single Forest AD domain ?
The current domain & forest functionality level is Windows Server 2003.
My current Domain controller are as follows:
HeadQuarter Office AD Site where all of the workstations resides:
OLDDC01: Windows Server 2003 – Running as: DC/GC, PDC, RID & Infrastructure Master Role and Primary DNS & DHCP (for all of the servers in HQ and the Workstations) to be decommissioned.
NEWDC02: Windows Server 2012 R2 – Running as: normal domain joined server (member server)
Data Center AD Site where all of the servers resides:
PRODDC01-VM: Windows Server 2008 R2 – Running as: DC/GC, Schema Master Role and Secondary DNS for all of the servers.
PRODDC02-VM: Windows Server 2003 R2 – Running as: DC/GC, Domain Naming Master Role (to be decommissioned)
PRODDC03-VM: Windows Server 2008 R2 – Running as: DC/GC, Primary DNS for all of the servers
In this first stage, I just need to Promote the NEWDC02 in my HQ to be the DC/GC and let it run, next week I’ll post new question for transferring the roles that is held by OLDDC01.
Any kind of help and assistance would be greatly appreciated.
