Exchange 2010 & Exchange 2003 coexistence and legacy DNS records
quick question for the experts - during a transition from Exchange 2003-2010 where I will have a period of coexistence, if I update the external and internal DNS A records that point to 2003 for OWA and make them point to 2010, do I also have to add the legacy.domain.com DNS A record on external DNS? I know that I have to setup the redirect property for the legacy OWA in Ex2010, but I am not clear on whether the redirect happens all internally or whether it actually redirects the user back to the Internet, upon which they would need an external DNS A record for the legacy.domain.com record?
So basically, I just need to know if I need to create a new External DNS A record for the legacy record (2k3 Ex FE server) or if I only have to do it on the internal DNS?
thanks.
