All of my servers are running 2008 R2. My 2 domain controllers are also 2008 R2, but running at 2003 domain and forest level. this is because I upgrade from 2003 a while back and we still had some 2003 Servers running. Now those 2003 servers are gone. I would like to raise my levels up to current 2008 R2. Not sure on what steps I need to take. I see alot of upgrading from 2003 and so forth. Any help would be greatly appreciated.

thanks Don

Exchange 2010 will not be affected by this change; will be transparent to users.
