I’m in the process of raising my Forest & Domain Functional Levels from Windows Server 2003 to either Windows Server 2008 or Windows Server 2008 R2. I’m looking for a recommendation as too which option to go with. I currently have 2 DCs which are Windows Server 2008 R2 and all of my workstations are Windows 7 Pro. I also have some Windows Server 2003 STD which are member servers and not DCs and will be working on retiring them in the next few months. Is there anything I need to do prior to raising the Forest and Domain levels? Should I raise the Forest then the Domain? Appreciate any recommendations and assistance. Thank you.
