    Question [SOLVED] Upgrading from 4.5.5 - Advice?

    Hi all - I posted this in another section but it probably belongs here...

    Hi all,

    I am currently running a FC4 box with zimbra 4.5.5. I recently moved my current install to newer hardware, so now I am ready to upgrade.

    So - what is the best way to upgrade the open edition 4.5.5 to say 4.5.11 on FC4?

    Should it be done one step at a time? 4.5.5 to 4.5.6, then to 4.5.7 and so on? Or can I upgrade all the way to 4.5.11 in one jump?

    My eventual plan is to get to 5.02 - however the issue becomes an OS upgrade (I am assuming Fedora 7) as well as a ZCS upgrade - which makes me nervous.

    Thanks,
    Rob

    You do NOT need to go stepwise thru all the versions. You should be able to go all the way to 4.5.11 in a single bound . You must be higher than 4.5.5 to upgrade to any v. 5 package (actually 4.5.7 and later I think), but there's no need to waste your time going through all the intermediate versions.

    Of course, though it should go without saying, we always remind you to keep a copy of your current (4.5.5) install binary and take a full backup of /opt/zimbra before you do your upgrade so if anything blows up you can get back to where you started.

    Cheers,

    Dan

    Thanks for the reply. I am 99% sure I will be upgraded to zcs 4.5.11 this saturday, but will still be on a FC4 box...

    So - where to go from here? I am thinking of the following:

    - I only have ONE box to upgrade, so no "intermediary" steps possible...

    Step 1 - backup

    Step 2 - install Fedora 7. Follow the instructions here http://www.zimbra.com/blog/archives/...er_server.html
    There is a zcs 4.5.11 install for Fedora 7. Versions match, so the move should be OK.

    Step 3: Upgrade 4.5.11 to 5.02.

    Any thoughts? Possible gotchas?

    Thanks,
    Rob

    You should be OK here as long as the version you're changing OS on is the SAME version before & after. You cannot, for example, back up your 4.5.5, install 4.5.11 on your new FC7 system, and restore the 4.5.5 backup from there. This wiki article should help you:

    Thanks,

    Looks like I am going...

    4.5.5 on FC4 -> 4.5.11 on FC4

    Then

    4.5.11 on FC4 -> 4.5.11 on FC7 (fresh install of FC7)

    Then

    4.5.11 on FC7 -> 5.02 on FC7

    Looks like three steps...

    Thanks,
    Rob

    The Zimbra website recommends to go to 4.5.10 first.
