Transferring FSMO roles from Windows Server 2003 to Windows Server 2008

Hello,

I have the following AD environment:

Functional Level: 2003
2 Sites
1 Windows Server 2003 = PDC, all FSMOs, Primary DNS, DHCP
2 Windows Server 2008 = Domain Controller, DNS
1 Windows Server 2008 R2 = Domain Controller, DNS

I will be transferring the FSMO roles to one of the Windows Sever 2008 DC.

I have a updates DPM System State backup (this includes Active Directory) of the PDC holding the FSMO roles, but will this backup be enough in case something goes wrong on the FSMO transfers?

After I transfer the FSMOs over, how can I verify that the FSMO roles were transferred properly and that they are working properly in the new 2008 DC?

If it does go wrong you could seize the roles, see the below article.

I would recommend to run dcdiag /test:fsmocheck /e from any DC after performed role transfer and this should pass

Thank you all,

Do I need to log off my users to perform this?

No its not required

Its not related to users, client computers and member servers

Ok, Thanks.

I will keep alive my Windows Server 2003 DC after the FSMO roles are transferred since its also our DHCP server and a file server (I will migrate these functions later on). Will it be problematic to keep it alive for some time?

Also, I have read in some articles that I have to reconfigure the time services when transferring the PDC role, does this apply to me?

You would need to change the time source to your new PDC if you plan to turn the old one off eventually

FSMO roles were transferred successfully. Logs reflects this successfully and when issuing NETDOM QUERY FSMO the new 2008 DC reflects to be the holder.

The old 2003 DC is still on production since it host our DHCP and is a File Server as well, these functions will be migrated in a couple of weeks.

Is there anything else that I will need to be aware of at this moment?
