I am having an NT domina with Exchange 5.5 and we are thinking of moving to 2003 AD with Exchange 2007. I think there isn't a straight upgrade path from 5.5 o 2007. Is it right? And how about should I go about the upgrade? New 2003 domain with 2003 Exchange and then moving onto 2007?
What's the best way to go forward? Ideas welcome.
