Exchange 2010 \ Domain Controllers
Just been reading around various blogs \ technet articles about the Exchange 2010 migration and some seem to suggest you need to have a 2003 DC in order for setup to complete correctly? It might alternatively be saying you need to have a minimum of 2003 SP1 (which makes sense) but the wording isn't clear enough to tell either way.
Also been reading if you're on 2008 R2 exclusively for DCs it can affect schema updates? Each site seems to be saying subtly different things so would be interested to hear from anyone who's done a migration from 2007 to 2010 how much of this is true...
- did you have a 2003 DC in place during the migration?
- have you kept a 2003 DC since?
- are you running 2008 R2 DCs and OS for the Exchange box?
