I'm planning to demote windows 2003 DC this weekend and after researching the process I believe following needs to be done and want to make sure my understanding is correct.
DC2003 running Windows 2003 (AD, DNS, DHCP, File Server)
DC1 running Windows 2008
DC2 running Windows 2008
Ran DCDIAG report attached.
DC1 has all FSMO roles.
All three domain controllers are global catalog servers.
Domain Functional level: 2003 (screenshot attached)
Steps to demote:
Remove DC2003 as a global catalog server. (maybe reboot afterward)
Change DC2003 DNS to point to DC1.
Run DCPROMO and keep this as DC2003 as the member server.
After successful removal change domain functional level to 2008
Should this change affect DHCP? Can I move DHCP role at the later time?
Am I missing anything?
Can someone please review this and let me if steps are correct?
