I need to take the last 2003 dc out of my 2008 R2 domain. I have transferred the fsmo roles and verified they have been transferred. We have also migrated to Exchange 2010. The dc fsmo roles transfer took place about 2 weeks ago and all logs and replication look good. We now have 2 2008 R2 Dcs both as GCs. The one thing I about forgot is transferring the time server role. However, several years back I set a GPO for time services at the domain level and it applied all DCs. I have check the registry of the 2008 DCs and the GPO is applied. With this GPO applied is there any need to do any type of tranfer of time services? Seems that I can just demote the 2003 DC since the fsmo roles have been transferred.
