Forgive me if this has been answered in another post, if it was did not locate.
According to Technet a 2012 DC will cause problems with Exchange 2003. Want to ultimately migrate to 2012 AD with Exchange 2010.
-- Initial thought was to add the 2012 as a DC and then install Exchange 2010 (I know should not install on a DC, but small office with only 8 users). Migrate mailbox and remove Exchange 2003.
-- Then was thinking because 2012 comes w/2 VMs maybe can install 2 - 2012 VMs one DC and the other for Exchange 2010.
Is this feasable without breaking Exchange 2003 or should the configuration be 2008 R2 DC, 2012 member server w/Exchange 2010?
