Just a few questions on raising Domain and Forest Functional Levels.
1. Once you have upgraded the Domain functional level, how long should you wait before upgrading the forest functional level?
2. By raising the root domain functional level, will this automatically raise any child domains or do we need to raise the level on the PDC of the root domain then raise the level on the PDC in the child domain? Or do we do the child first then the root domain?
3. What is the best way to recover if things don't go to plan? For e.g With a root domain with 2 DCs and a child domain with 5 DCs?
4. If we are running at Windows 2000 native domain level with all Windows 2008 R2 servers, can we raise the domain functional level straight to Windows Server 2008 R2?
