The ELevate project aims to upgrade a cPanel installation with minimal outages. It builds and expands on the Alma Linux ELevate project, which was created for in-place upgrades of RedHat-based systems.
Pull requests are welcome. Code contributions are subject to our Contributor License Agreement
This project will perform the following upgrades:
- CentOS 7 to AlmaLinux 8
- CloudLinux 7 to CloudLinux 8
- Ubuntu 20 to Ubuntu 22
The ELevate provides a wrapper around existing upgrade projects. While these projects are very effective at upgrading distribution packages, if you attempt to use them directly on a cPanel installation, you will end up with a broken system.
cPanel's ELevate wraps the following projects:
- RHEL-based systems: The LEAPP Project.
- Ubuntu-based systems: The do-release-upgrade script.
For more information about the project, you can watch our 
.
The cPanel ELevate project checks for any blockers before it starts the upgrade process. The process is performed in stages. The server reboots between each stage and then does a final reboot when the process is complete.
Install the elevate-cpanel service.
Update the system's distribution packages, disable any cPanel services, and set the message-of-the-day (motd) to inform users an upgrade is in process.
Configure the ELevate repository.
Update cPanel packages, remove any conflicting packages, then back up the existing configuration. NOTE: The backup not include any of the system's data. However, it might include the configuration for the following software:
- cPanel (
upcp) - EasyApache 4
- MySQL or MariaDB
- Distribution Perl/PECL binary re-installs
The system may ask you to provide answers to some questions before it can start the upgrade process.
Upgrade the server to the new distribution and restore the removed packages.
Verify the installation and clean up the server. This includes removing the elevate-cpanel service.
To start the ELevate process and upgrade your server, read our ELevate Your Server documentation.
