    Exclamation upgrade zimbra ...

    I have installed Release 4.5.4_GA_763.RHEL4_20070326134650 CentOS4 FOSS edition. My users pick up mail by imap. I want to install version 5.05 or 5.06.
    That I must make to maintain mailbox of each user?
    The backups of version 4.5 is used for version 5?

    Saludos

    -Pick a backup method out of: Open Source Edition Backup Procedure - Zimbra :: Wiki Rsync, cp, lvm, snapshots, disk image etc, and there's tons of other FOSS backup methods listed throughout the forums.
    -I would stop off at at least 4.5.11 before making the jump to 5.0.6, as there's lots of tomcat & ldap changes around 4.5.6/.7 to account for (.6 has a clamav bug though that can be tricky on mail delivery).
    -Read the 4.5.11 release notes
    -Upgrade to 4.5.11
    -Verify your 4.5.11 works
    -Make another backup (you got this far, might as well not go all the way back to 4.5.4 if something goes wrong to the jump to 5.0.6)
    -Read the 5.0.6 release notes
    -Upgrade to 5.0.6
    -Test & relax if all went well

    Should you have to revert you'll need to clear your /opt/zimbra > copy in the backup > run the 4.5.4 installer (or if restoring the 4.5.11 backup it's installer)
