Raising Forest and Domain level with RODC

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?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Rasing the Functional Level should only be done when ALL of the DC's are at the same level. However rasing the functional level only affects the R/W DC's but the configuration still gets pushed to the RODC's. Make sure that the RODC's are upgraded as well before perfoming the Functional Level Raise.
