How to Migrate CentOS 7 cPanel Server to Almalinux 8

CentOS Linux was discontinued at the end of 2021 in favor of CentOS Stream. CentoS 7 will continue to be supported through the remainder of the RHEL 7 life cycle, which will end on June 30, 2024. If you are using CentOS 7 server with cPanel, it is better to upgrade to AlmaLinux 8, which is a clone of RHEL 8 supported by cPanel.

cPanel provides an open-source script to upgrade your CentOS 7 installation to AlmaLinux.

Download elevate-cpanel

To download elevate-cpanel, run

wget -O /scripts/elevate-cpanel https://raw.githubusercontent.com/cpanel/elevate/release/elevate-cpanel
chmod 700 /scripts/elevate-cpanel

Update the server

/scripts/upcp

Reboot the server

reboot

Check for upgrade blockers

You need to run this script to see if any software installed on your server is computable or not.

/scripts/elevate-cpanel --check --upgrade-to=almalinux

If there is no problem detected, you can run the upgrade script.

Upgrade to AlmaLinux 8

To upgrade to AlmaLinux, run

/scripts/elevate-cpanel --start --upgrade-to=almalinux

Server will auto restart during the upgrade process. Once it is finished, you will have AlmaLinux 8.
