  • Exchange 'Upgrade' Advice sought

    Hi all,

    I need to upgrade from Exchange 2003 Standard to Enterprise and I am just wondering on the best way to do this. The Exchange Enterprise will be on a new server so should I just add this onto the Domain as an additional server (is this possible with two versions of Exchange?) and just move the mailboxes over? If this is the best way to do this should I decommission the current server when finished? Is there anything I need to do for this?

    Can I rename the new box so that it has the same name as the current server or should I just leave it as the new name and make changes to DNS and A records. I also assume that I will need to change the Outlook settings so that they point to the new server as we have Outlook 2000 and I assume this will not change automatically, even with a mailbox move.

    Or am I barking up the wrong tree completely and there is a better way to do this?

    Cheers

    Jim

    Forget that it is Enterprise edition for a moment, as that has nothing to do with the procedure.
    If you have the hardware, then do a standard swing.

    Zero risk, no downtime and you can take your time.

    Just ensure that you have patched it with Exchange 2003 Sp2 plus the post SP2 updates before moving any mailboxes.

    Outlook will redirect automatically, although I would suggest an upgrade to Outlook 2003.
    No need to do anything with your public DNS records, just change the NAT on the firewall.

    DO NOT RENAME THE SERVER as that will break Exchange.

      Hi Simon,

      Thanks for your reply.

      It all looks reasonably straightforward; the only query I have is with the comment 'No need to do anything with your public DNS records'.

      I currently have a FQDN of servername.domain and I have a public A record pointing to this Hostname. If I changed the Hostname would I not also need to change this for my Domain?

      Cheers

        Your internal and external DNS are different - unless you are in the unlikely event of using public IP addresses internally.

        Personally I would never use the server's real name for anything on the Internet. I use common names like mail, post, exchange etc for the DNS name of the server on the Internet and then the server's real name is used internally. That way I can move services around and all I have to do is change the NAT on the firewall.

        Therefore if you are using the server's real name, this might be a good opportunity to change it around to a generic name. Leave both servers running while you do so.

        However don't forget that you can have multiple DNS entries pointing at the same IP address, so if you do change things then you can simply add the new name to the DNS, change the MX record to match, wait 48 hours and remove the old name with no loss.

        Simon.

          Makes sense. I'll use this as an opportunity to change things around!

          Thanks again for your help.
