Upgrading from 2000 to 2003 on a new server

Posted on 2007-04-06

HI All,
I am currently running Exchange 2000 on a Windows 2000 box (We will call this OLDSERVER1).  This box is going to be retired.  I am installing a new box with Windows 2003 and Exhchange 2003 (We will call this NEWSERVER1).  My plan is to add the 2003 box, install Exchange 2003 on NEWSERVER1, migrate the mailboxes from OLDSERVER1 to NEWSERVER1 and then uninstall the OLDSERVER1 from the network.  I have three questions:
1. Are their any good articles out there for doing this. I have done this before, but it was a while ago.

2.  My client computers are running outlook.  Each one of them is using the MS Exchange service and are pointing to OLDSERVER1.  How can I make them point to NEWSERVER1without having to go around and reconfigure each workstation.  

3.  I remember reading that you their were certain Public Mailboxes that you do not move.  Is this correct?

Any help would be greatly appreciated.

you can check
it has all the steps for the migration
you need to replicate the system and public folders first and then move the mailboxes over to the new server
once the mailbox is moved to the new server, outlook should automatically point to the new server (when both the servers are running).

What happens when I remove the Old Server, will Outlook still point to the new server?  After I replicated the System and Public folders, what how do I break the relationship that I have created between the two servers?

once you have replicated the system and public folders and moved the mailboxes over to the new sever, you need to change the RUS, OAB and Routing master server to point to the new server
once that has been done, stop the exchange services or shut down the old server for few days, just to be sure that user's don't face any issue when the old server is not running
if the users don't report any problem then you can run the exchange setup on the old sever and select uninstall

when you move the mailbox over to the new server, wait for sometime for the information to replicate. once that has been done, open outlook and it should automatically discover the new location of the mailbox. after that outlook will start pointing to the new server.
