    Default Zimbra V5 on SLES 9?

    My Zimbra server is running SLES 9 with Zimbra V4.5.
    Can I upgrade to Zimbra 5 (which says it is for SLES 10) WITHOUT upgrading my opsys or is this asking from trouble?

    It's also an unsupported option if you're an NE customer. The version of Zimbra for SLES10 has not gone through QA on SLES9, my advice would be to upgrade to SLES10.

    Default Upgrading from SLES9 to 10 and from Zimbra 4.5 to 5.0

    Ok, upgrading SLES is no sweat. They permit upgrading an existing system without disturbing user directories, etc.

    So for my situation would this be the recommend procedure?
    1. Cold backup of Zimbra (of course!)
    2. Stop Zimbra
    3. Upgrade SLES9 to SLES10
    4. Upgrade Zimbra 4.5 to 5.0 BEFORE attempting to start Zimbra under the new SLES10
    5. Start Zimbra 5.0 under the new SLES10 opsys

    Any other considerations or things you would do differently?
    Thanks for the help.

    That's fine, but it'll be far easier to troubleshoot any issues if you split the OS vs ZCS upgrade into 2 parts:

    1. zmcontrol stop (ps aux | grep zimbra & kill leftovers) (Make sure /opt/zimbra/redolog/redo.log is owned by zimbra after zmcontrol stop - seem to remember a known issue with this changing after stop on 4.5.x SLES9 & Debian3 - LMStone might know specifics about any other swatch or logger tips when going to v5 but I think there's no showstoppers.)
    2. Backup your /opt/zimbra & any other linked locations
    3. Put on the 4.5.11 SLES9 binary, if not on that version already.
    4. Disable zimbra in chkconfig/rc.d/init.d
    5. Upgrade SLES9 to SLES10.
    6. Run the 4.5.11 SLES10 binary (./install.sh -s should be fine, probably no need for the zmsetup.pl on this one, as long as your on 4.5.11 already from step3 - doesn't hurt to run it in entirety, just mentioning a shortcut if your time crunched.)
    7. Zimbra should be enabled on start up automatically after this install, but might double check.
    8. Run the 5.0.11 SLES10 binary (entire install script).
    9. Take another backup; nice to have a fresh 5.0.11 to restore to instead of that 4.5.x SLES9 copy.
    10. Test mail delivery, then celebrate with favorite/appropriate cold beverage.

    That's a good list! Thanks.
    How do I check my current Zimbra version to make sure I'm on 4.5.11? Or does it matter? The 4.5.11 install is just to get my 4.5.xx Zimbra converted over to SLES10 before upgrading to 5.0.11, right?

    My Zimbra version is 4.5.10_GA_1575.SuSEES9 Nov. 17, 2007

    Still do the upgrade to Zimbra 4.5.11 SLES10 after the upgrade to SLES10 and before the Zimbra upgrade to 5.0.11?

    zmcontrol -v

    Yes, like I said the 2 phase method may not be required, but there's a reason we released SLES10 binaries for 4.5.11 (they're not available 4.5.10 prior) - to make this upgrade or migration process easier (plus you should especially step through 4.5.11 if there are LDAP replicas in play).

    You can find the 4.5.11 SLES 9 & 10 binaries here: http://www.zimbra.com/community/downloads_previous.html
    And 5.0.11 SLES10 here: http://www.zimbra.com/community/downloads.html
    (Based on your other posts I assume this is FOSS.)

    Following this procedure, should I start Zimbra after Step 3 to make sure it will start? Same question after Step 6. Thanks!

    The installer will start Zimbra when it finishes - so if you want, step 3a & 6a could be: "test clients & mail delivery".
