    Default Updating Linux Break Zimbra?

    Hello,

    I'm running Zimbra on CentOS 5.3 and I'm extremely nervous about just running yum update. Is there any chance running yum update to update the OS could break Linux?

    I just have this paranoia that maybe if java or something that Zimbra was developed in updates and its not backwards compatible and something in Zimbra breaks.

    Am I being too paranoid? Thanks in advance.

    Pretty much all dependencies ZCS requires are held within /opt/zimbra and distributed as part of the package. I do not believe you will have any issues upgrading to CentOS 5.3. Though every upgrade is different, dependent on what other packages have been installed, so please remember to take a full backup

    i remember several weeks ago, for some reason, i installed another version of perl by using "yum". although i'm not 100% sure, it seems to caused my zimbra failed to operate. just fyi !

    was that from the standard repos or a third-party ?

    I've had problems with standard CentOS repo's upgrading and enabling services (e.g. Sendmail). After reboot, Zimbra was unable to start, due to ports already taken by other programs which should've been disabled.

    If services are disabled they should not re-enable. Numerous upgrades and no issues

    Probably user error. :-) Thinking about that situation, it's possible the service was just stopped, rather than disabled. But I have had issues similar to that - existing services changed behavior, and I didn't read release notes for the updates.

    Well, I upgraded CentOS 5.2 -> 5.3 with Zimbra 5.0.13 installed - no problems.
    Later upgraded Zimbra 5.0.13 -> ... -> 5.0.18. - no problems.
    I upgraded CentOS 5.3 -> 5.4 with Zimbra 5.0.18 - no problems.
    Later upgraded Zimbra 5.0.18 -> 6.0.2 - no problems (minus my whole 5.0.18 logs gone. Sadly, Zimbra 6.0.x starts logs from scratch.)

    When upgrading CentOS from 5.3 -> 5.4, I followed these commands from this site, which worked:

    Code:
    yum clean all
    yum update glibc\*
    yum update yum\* rpm\* python\*
    yum clean all
    yum update
    shutdown -r now
    Check your new version with

    Code:
    lsb_release  -a
    Good luck!
