We have an AD forest with 3 Server 2008R2 DCs and a dozen Server 2008 Read Only DCs at remote offices. The forest and Functional level are still at 2003. I looked everywhere and could not get a definite answer to this. Can we raise the functional level to 2008R2 or only 2008. I know all full DCs have to be at 2008R2 for that forest and domain functional level but do RODCs count also?
