Backups before Centos7 to AlmaLinux8 Migration




  • Andrew

    Why don't you handle the upgrade yourself then or hire a professional to do the work for you?

    I would do the old school way and run a manual cPanel backup of all ccounts including system config files then store those off-site till the upgrade is completed.

    • PHP 7.4 and up are still supported by Almalinux so you should be good to go there.
    • Alma doesn't support MySQL 5.7 so yes you need to upgrade this beforehand either to MySQL 8 or to MariaDB 10.4+
    • cPanel doesn't support snapshots

    Hey there!  I'll go through and answer what I can for you.

    A flat-file copy of /home and /var wouldn't be enough to properly restore the sites and databases.  You'll want to create account backups.

    1 - That's entirely up to you.  The WHM >> Backup Configuration tool has an "additional destinations" tab where you can send the backups to a remote server so they aren't stored on your machine, but if you want additional control over the backups, JetBackup is a great tool.

    2 - Yes, I would test and upgrade things as much as you can now before making the change.

    3 - If possible, yes.

    4 - I would only worry about this if you'd made customizations to the server.  When they transfer your settings they can also move all the configurations listed here:

    5 - cPanel doesn't have a snapshot tool to take an image of the whole machine

    6 - As long as you have full account backups, that will contain everything necessary to restore the accounts to a new machine if necessary.
