🗒 Tutorial

Details

The following tutorial provides step-by-step procedures to automatically switch a CentOS 8 instance to Oracle Linux 8 by removing any CentOS-specific packages or replacing them with the Oracle Linux equivalent. As the README.md states in the Oracle centos2ol repository on GitHub, the script used in this tutorial is a work-in-progress and not designed to handle all possible configurations.

Please ensure you have a complete backup of the system before starting this process if the script cannot successfully convert the system.

Be sure to review the centos2ol project README.md file for the latest details.
