I'm on a 2003 AD functional level on Server 2003 Std domain controllers. I am in process of migrating from Exchange 2007 to Exchange 2013. After reading the Exchange 2013 support matrix I need to make certain I understand my migration path correctly. I am adding Server 2012 R2 DCs into my AD environment in preperation for this project. However, I had mistakenly thought that Exchange 2013 was not supported on a 2003 functional level domain, but after reading the support matrix that appears incorrect.
My questions are these:
Is Exchange 2007 supported on a 2012 domain so that I can raise the functional level now rather than later.
Or, should I stay on a 2003 functional level until after the migration to 2013 is complete?
I'm getting a headache trying to get my mind wrapped around this. Maybe I'm getting too old.
