I've poured over the literature regarding upgrading from Exchange 2003 to 2010, and have a fair idea, however I have a question which seems not to be covered :-
What is my best route to follow, if I want to replace my existing OWA with a 2010 OWA ?
In other words, the old OWA and new OWA will not run together - old one is to be killed off before AD prep . . .
All the sites mention using DNS entries for legacy.place.com as well as current.place.com
Does this fall away for only having a new 2010 OWA, and my clients will then run through 2010 OWA to either the Exchange 2003 or 2010 mailboxes, on our existing owa.place.com address ? Our mailbox migration will take a while, so I need both to co-exist . . .
Thanks in advance !
