    Welcome to the forums,
    What version are you currently running? (zmcontrol -v)

    OS Release notes: NE Release Notes.pdf

    Multi-Server Environment Upgrade Steps:

    Before you begin, you should stop all the servers in your ZCS non-production
    environment. On each server, at zimbra, type zmcontrol stop.
    Important: Upgrade the servers in the following order: LDAP server, mail store server, and then MTA server.

    Log in as root to the Zimbra server and cd to the directory where the 4.5.6 tar file is saved (cd /var/tmp).
    Type the following commands:
    tar xzvf zcs.tgz, to unpack the file
    cd [zcsdirectoryname], to change to the correct directory
    ./, to begin the upgrade installation

    Note: If you have a large number of accounts, include nohup on the ./ command line. (nohup ./ so that the session does not time out before the configuration has been upgraded.

    Do you wish to upgrade? [Y] is displayed, press Enter to continue.
    The upgrade packages are unpacked.
    The packages you want to install on the server should be marked Y. All other packages should be marked N.
    The system will be modified. Continue? is displayed, type Y and pess Enter.
    The upgrade process verifies which version of ZCS is being run and proceeds to upgrade/the older packages are removed.
    Config is restored.
    Automatic restart of processes
    The upgrade is complete.
    Continue to upgrade each server.

    Important: After you upgrade all servers, you should run a full backup immediately. Schema changes in this release invalidates all old backups.

    Note: If your users are affected by the 2007 time zone changes, you should run the time zone migration tool.
