    Exclamation Upgrading from 4.5.6 to 5GA

    Hi,

    My environment consists of a zimbra installation on a Debian 4 box, based on How to install Zimbra Debian 3.1 binaries on Debian Etch 4.0 [Workaround]

    Now that 5GA is out, I am considering upgrading. However, given the above hack (I've changed /etc/debian_version back to 4.0 after the installation), I'm not sure how clean the upgrade would be.

    Has anyone else tried this yet? Any pointers? Backup, backup, backup goes without saying!

    Best,
    A

    Zimbra is working on the upgrade procedure for a smooth transition from 4.5 to 5.0. If you attempt this migration, it may fail.
    -Read this thread /forums/administrators/13736-solved-5-0-ga-debian-4-a.html (essentially the same setup as you)
    -Glance at /products/sunset_binaries.html
    -& keep an eye on the announcements section

    In the meantime, you can get yourself prepared for a quick 4.5.11 hop by going from 4.5.6 > 4.5.10
    (Plus there's a ton of ldap & tomcat performance enhancements in that perticular jump as well.)
    You can find 4.5.10 here: /community/downloads_previous.html

    Always make a backup each time before you upgrade, at the very least (giving you the simplest aside from disk images etc) this could involve doing:
    su - zimbra
    zmcontrol stop
    exit
    become root
    ps aux | grep zimbra (kill -9 pid# of any remaining processes)
    mkdir /zcsbackuprsync
    rsync -avHK /opt/zimbra/ /zcsbackuprsync/zimbra
    mkdir /zcsbackuptars
    tar -zcvf /zcsbackuptars/backup.zimbra.version.date.time.tar.gz -C /zcsbackup/zimbra .
    -Then you can mv or scp /zcsbackuptars/backup.zimbra.version.date.time.tar.gz /elsewhereAsDesired
    -Have the old installer handy & already downloaded just in case you need to restore.
    -Use the stuff in /zcsbackuprsync/zimbra which is still there unpacked/ready to go in order to get yourself up and running faster.
