I'm working on an upgrade from Exchange 2000 Standard to Exchange 2003
Enterprise and have some questions about my migration strategy. Here's a
brief rundown on the environment, both in the same AD environment:
Server A
-Exchange 2000, SP3
-Windows 2000, SP4
Server B
-Exchange 2003, SP1
-Windows Server 2003 Standard
Our users are accessing their email in different ways; OWA, POP3 and
Outlook. We're trying to do a gradual migration and I was wondering if this
will work. Here's what I was planning:
1. Set up Server B as a front end server.
2. Point MX , POP3 and OWA DNS to Server B.
3. Migrate Outlook user's mailboxes from Server A to Server B.
4. Gradually migrate POP3 users so I can import their mail.
5. Bring Server A down.
The questions:
Will this work? ;-)
Can Exchange 2003 be a front end server without Exchange 2000 being a back
end server? Is that necessary?
Can mailboxes exist on both servers even if Server B is a front end server?
If so, can POP & OWA users whose mailboxes are on Server A still get their
email externally (Internet) through the front end server?
Sorry for the long post, I was just trying to be thorough. Thanks in advance
for any help!
