  • Exchange Server 2003 to 2007

    Hi All

    I have set up an exchange 2007 server on our network, moved all the mailboxes over from the exchange 2003 server and everything is running ok, but i have an exchange 2003 sat doing nothing apart from recieving emails and forwarding them to the exchange 2007 server. The exchange 2003 (server 1) ip address is for example: and the exchange 2007 (server 2) address is Now server 1 will receive emails as that is how it is set up on our firewall and our external dns.

    How on earth do i set it so i can get rid of exchange 2003 - server 1 and put the exchange 2007 - server 2 on the address?

    I have tried moving server 1's address to something else and changing server 2's ip address to but unfortunately i couldnt get OWA and outlook to talk to it, it was still trying to look for server 1 on

    Please help

    Why don't you just change the firewall rules? I wouldn't be changing server IP addresses just to get pre-existing firewall rules to work. The hassle involved doesn't compare.

    On a slightly different note - do ensure that you complete every step in this article before removing the old server:
