    I'm currently running CPanel 11.25.0-R46156 - WHM 11.25.0 - X 3.9 on
    CENTOS 5.3 x86_64.

    I would like to upgrade the OS to CENTOS 5.5.

    What are the dependencies of updating the OS? Can I just update the OS and CPanel will continue to run or will I need to run an update on CPanel as well? I'm very new to CPanel.

    Cheers,

    N00b

    Rule of thumb since CentOS 5.1 has been that you can update CentOS or RedHat Enterprise Linux at any time without issue. Keep in mind that if you had automatic updates enabled, you would already be on CentOS 5.5.

    I am running on CentOS 5.5 myself and have not had any issues yet.

    Also keep in mind that a yum update is not going to get things like MySQL, Apache, or PHP which you have to manually upgrade within cPanel.

    Actually, cPanel/WHM automatic updates will update MySQL but not automatically bring you to a new major version. For example, if you're on MySQL 5.0, you'll get updates for 5.0, but you wont be moved to version 5.1. That's where manual intervention is required for MySQL.

    You are correct for Apache and PHP, those need to be manually upgraded via EasyApache.
