    Default 32-bit to 64-bit Migration on New Hardware

    I have a small ZCS installation (/opt/zimbra is about 92GB, 60 users) running on RHEL 4 32-bit.

    I want to move it a new server running RHEL 5 64-bit.

    Are there any drawbacks to doing a completely new installation, exporting the mailboxes on the older server, and reimporting them on the new server?

    Shares? Are you speaking of shared calendars and folders? If so, that's not an issue with this particular installation.

    Why would you do this, you need to setup LDAP and accounts, tec. again before reimporting them on the new server. A much longer path the to follow the Zimbra WiKi way:

    Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki
    I think its pretty much working! Used it 2 times already, pls. read the forum first!

    It just seems that getting it right is so difficult. I searched the forums and there are tons of issues with migration.

    Don't get me wrong, if I had a large installation, I wouldn't even consider my earlier idea. I hope that someday Zimbra has a simple Zimbra to Zimbra migration tool that will work regardless of operating system (RHEL, SUSE, etc.) and platform (32-bit or 64-bit).

    But, please, if anyone else can list other issues I'll have to address, please do so. I appreciate the input. You might just change my mind.

    Seeing that no one has any major issues with my plans, I'm wondering if someone with some scripting skills can help me automate the task.

    I know that I can export from the command line like the following

    Code:
    /opt/zimbra/bin/zmmailbox -z -m user@domain.com getRestURL “//?fmt=tgz” > /tmp/account.tgz
    And that I can likewise import mailboxes on the new server:

    Code:
    /opt/zimbra/bin/zmmailbox -z -m user@domain.com postRestURL “//?fmt=tgz&resolve=reset” /tmp/account.tgz
    If I could have a script that would cycle through all of the accounts on the old server and export them as separate files, having the email address/user as the file name, I'd be cooking.

    Thanks in advance!
