    Default Step-by-step guide on upgrading Zimbra

    Below is my prepared step-by-step guide on upgrading my Zimbra from version 6 to 7 tomorrow. Let me know if I have missed out any important steps or having un-necessary steps:

    0. Schedule a Full backup tonight

    1. Download the latest version at: Network Edition Downloads: Enterprise Messaging and Collaboration Software by Zimbra

    2. Transfer into tmp folder (for me, it's NFS storage mapped into Zimbra)

    3. tar xzvf zcs-NETWORK-7.2.0_GA_2669.UBUNTU8_64.20120410002020.tgz

    4. cd zcs-7.2.0_GA_2669.UBUNTU8_64.20120410001942 (stop here today)

    5. service zimbra stop (begin upgrade process tomorrow)

    6. Take snapshot (I'm running Zimbra on ESXi 4)

    7. screen ./ (screen is recommended by Zimbra)

    8. /opt/zimbra/libexec/zmdbintegrityreport -r (fix any corruption in the database)

    9. sudo zmcertmgr createca -new

    10. sudo zmcertmgr deployca

    11. zmcertmgr deploycrt self -new

    12. su - zimbra

    13. zmmailboxdctl stop

    14. /opt/zimbra/libexec/scripts/

    15. zmmailboxdctl start

    16. zmprov fc -a license (to immediately flush the license cache)

    17. service zimbra start

    I have upgraded successfull. But take note of some issues:

    1. sysstat and sqlite3 are optional items ("suggested"). It's alright to continue if these are not found.

    2. If you do not use proxy server, please do NOT install memcache and proxy when prompted. memcache is known to cause problems.

    3. Remember to run /opt/zimbra/libexec/scripts/ Not sure if I can run this now without downtime...

    4. The logo sizes have changed!
    120x35 > 200x28
    450x100 > 300x48

    5. All the notebooks are suppose to get migrated into the briefcase as the documents tab will be removed in version 7 (making Zimbra less of an collaboration suite, why???). Unfortunately, I notice that only old documents are migrated and all the newer ones are gone!!! I have raised a support case to get Zimbra support to recover them from our backup.
