Exchange 2000 migtration and OWA
Posted on 2004-08-31
I have Client who is running Windows 2000 AD native and Exchange 2000 native as well. They have two Exchange 2000 back-end servers and one front-end server. The front-end server has OWA 2000 running on it.
They want to go to Exchange 2003 first then upgrade their Windows 2000 domain to Windows 2003 domain.
My recommendation to them was:
1. Apply the latest Windows services packs on all the domain controllers
2. Apply the latest Exchange 2000 service pack on all Exchange 2000 servers
3. Run the Exchange Forestprep and then the domainprep
4. Install new Windows 2003 server in the Windows 2000 domain
5. Install Exchange 2003 on the new Windows 2003 server and join the existing Exchange 2000 organization.
6. Apply Exchange 2003 SP1
7. Logon to Exchange 2003 server and use (Not Sure though) the migration wizard or the ESM to move the mailboxes from Exchange 2000 to the new Exchange 2003 server.
8. Public Folder (They have public folder tree enabled) I'm not sure what to do to migrate the PF to Exchange 2003 server. Should I use the PFMigrate tool? Or create a replica? Should I rehome the PF folders? Or do nothing since the servers are all in the Exchange 2000 organization.
9. What should I do with the RUS?
10. They have OWA 2000 at the front-end server and they want to go to OWA 2003. Should I do Exchange in place upgrade on the server and would that upgrade OWA automatically?
11. Since the client will move the mailboxes from Exchange 2000 to Exchange 2003 at phases, can the end users use the Exchange 2003 OWA to access the mailboxes on the an Exchange 2000 servers?
