How my Outlook clients can connect to a new upgraded Exchange server without changing their previous configuration

Posted on 2007-10-02

After a transition from Exchange 2003 to Exchange 2007, and after decomissioning the 2003 server, I want my users (outlook clients) to point to the new Exchange 2007 server, without modifying their configuration, if not it's gona be too much work.
I know  I can give my new server 2007 the IP address of the old server 2003 , but what about the name.
You can't rename an Exchange server, so what has to be done to make that possible.

    Are the servers going to be in the same Exchange org?

    If you leave the old server online after you move the mailboxes then when the users start the outlook client the outlook profiles will update automatically to the new server.

    As long as both the old and the new server are alive with Exchange services running when the users connect for the first time, Outlook will redirect automatically. No user or admin intervention required.

    Thank you guys for your answers, you are just great.
    I have an other question though; if you keep your 2 servers running.
    During the migration you have transfered the roles, so the exchange 2003 is like a kind of gateway betwen the users and the new server 2007.
    When is the time to take it off from my network. After one week, one month. Or is there a way to know that.
    Thank you for all.

    I normally leave the old server active for two weeks after a migration. During this period I'll try to shut it down for two whole days and listen for complaints that could highlight problems that need to be fixed before the server can be decomissioned. But I think this may be down to personal preference!
