    Default Zimbra Version 4.0.4 to Zimbra 4.5.6_GA Migration

    Hey Guys,

    I have an older server running Version 4.0.4_GA_457.RHEL4 Nov 15, 2006.

    I have a new fresh just built server running Version 4.5.6_GA_1044.RHEL4 Jul 6, 2007.

    What is the best way to go about moving all settings - server configuration (theme graphics, settings, etc) and also moving all users to the new box.

    Unfortunately due to running out of hard drive space on the old server it wasn't possible to 'upgrade' it.

    Basically I want to get everyone to the new server and do away with the old - without losing anything.

    Do you have custom skins? You'll need to back those up.

    Also, what OS are you migrating from/to?

    generally, you can just zip up /opt/zimbra and move it over following the wiki instructions.

    Are you serious? I am migrating between different versions, surely I cant just grab /opt/zimbra and move it.

    I am going from a CentOS4.5 physical box to a CentOS5 VM Server on very big hardware.

    Yup. Serious.

    You'll need to install your old version of zimbra on the new server 1st, then rm it, and move your new one in.

    It's very easy. It doesn't come without hiccups tho, but we'll get to those when we get there

    OK, you missed what I said. I have a new server WITH 456 already installed. And this isnt the open-source version, it's the licensed version.

    What did I miss? Do you have people on the new box already?

    Default No, thats right

    You want to migrate first, then upgrade.
    • Install the exact same 4.0.4 on the new server
    • Rsync the /opt/zimbra over from the old
    • Re-run the 4.0.4 install script on the new server
    • Start up the 4.0.4 on the new server and make sure it's running properly (LDAP, MySql, message store, etc) Really make sure - you don't want to try to upgrade a broken system
    • Shut Zimbra down and then -
    • Then run the install script for 4.5.6
