I plan to install Exchange 2010 which requires domain level 2003.
The current environment: Windows 2003 domain controllers. Single forest, single domain.
Head office: DC1 has RID, PDC, Infrastructure role
Site A: DC2 has domain naming master and schema master toles..
Site B: DC3
Forest level: Windows 2000.
Domain level: Windows 2003.
Q#1. Any issue with the above mismatch?
Q#2. How to raise the forest function level given domain level is already 2003?
Q#3. How to prepare a fallback plan just in case the change is unsuccessful or causes unexpected issue?
