I am making preparations to upgrade our primary domain controller to Windows Server 2008 R2 and am finding that I have questions that I can't seem to find answers to.
If I upgrade my PDC to Server 2008 R2 and have 3 other Server 2003 machines as BDCs, can the 3 Server 2003 machines be used to support a full featured Windows 7 Workstation environment with Roaming Profiles?
Keeping in mind that hose Server 2003 Servers will eventually be phased out in favor of Server 2008 R2 machines, are there any disadvantages that are great enough that I would be better off to upgrade the operating systems on all servers now?
When it comes to Active Directory, I have never set up a mixed Domain like that before. I suppose I would like to discuss what the disadvantages of the Mixed Server Domain are, compared to making a full switch to a pure Server 2008 SR2 Domain...
