    Default Migrate CentOS 5 w/ 6.0.6 Network 32bit to Ubuntu LTS 8.0.5 ZCS - ?

    My org was brought into a small office running Zimbra and I'm getting familiar with it, but would greatly appreciate some experienced oversight in my migration plans that I've pulled together from various docs on the wiki. We're pretty far behind and I'll be doing bare metal backups before I do anything, but if I don't need to use those, that'd be peachy. :-)

    The current server:
    32-bit aging Dell server
    CentOS 5
    Release 6.0.6_GA_2330.RHEL5_20100505191632 CentOS5 NETWORK edition.

    The ideal target: (I could be convinced to go CentOS, just a preference.)
    64-bit VMWare Virtual Machine
    Ubuntu Server 12.04 LTS
    Zimbra 8.0.5

    1. Upgrade current server to 7.2.5
    2. Build an interim Ubuntu 10.04 LTS server with a virtual drive dedicated to /opt
    3. Install 7.2.5 on the interim server (VM)
    4. rsync /opt from current server to interim server and re-run the installer
    5. Shutdown current server
    6. Fix all the problems
    7. Install Ubuntu 12.04 LTS onto a final server (VM)
    8. Snapshot the /opt virtual drive
    9. Shutdown the interim server
    10. Disconnect the /opt virtual drive and attach it to the final server
    11. Install Zimbra 8.0.5 on the final server
    12. Fix all the problems


    Any crazyness in that plan or even just cautions? Thanks!

    Why don't you take the easy route and use ZeXtras?

    You basically install a new server on your choice of operating system (CentOS is my recommendation) then install ZeXtras on the servers and go through the steps to move your users and server settings to the new server et voila, a new server running ZCS 8.0.6 (it should be out soon) without the hassle of move or upgrading ZCS. You want to make sure the original server is at the minimum required for running ZeXtras, I can't remember what that is offhand but it's on the ZeXtras web site. Obviously take a backup before upgrading any ZCS server.
