    I upgraded from 4.5.9 to 4.5.10 yesterday without incident.

    Always backup prior to upgrade!

    Default Is the upgrade safe yet?

    I'm currently running Release 4.5.6_GA_1023.RHEL4_64_20070627170359 RHEL4_64 NETWORK edition.

    Is it safe to perform the upgrade from 4.5.6 to 4.5.10?

    During the 4.5.5 -> 4.5.6 upgrade, the application server stopped working and I ended up contacting emergency support. It was a known problem with an easy fix.

    Are there any problems like this with the 4.5.10 upgrade?

    I saw this link called " Upgraded to 4.5.10 now all accounts locked out", but it sounds it could be a memory problem.
    Thanks for any advice,

    The link you've quoted is a memory problem. You should take a full backup of your system (as everyone should ) and do the upgrade.

    Thank you for the quick response. I completed a full backup from the Backup and Restore documentation.

    [zimbra@mail ~]$ zmbackup -a all -f
    full-20071125.204228.864


    On another note, a symlink (backup -> /zimbra_backup/backup/) has been created from to send backups to a different internal drive.

    Will this have any impact on the update?

    Thanks,

    David

    I don't believe it should make any difference but, obviously, make sure it's still pointing to the same location after the upgrade.

    I stopped the Zimbra services using zmcontrol stop and started the installation as root.

    The install seemed to start OK, but I got this error:

    Checking for a recent backup
    WARNING: Unable to find a system backup started within the last
    24hrs. It is recommended to perform a full system backup and
    copy it to a safe location prior to performing an upgrade.

    Do you wish to continue without a backup? [N]


    I just performed a backup before running the installer. Should I change the way the backup is performed, or am I ok to go forward with this?

    Thanks for all the help.
