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.
