Convert from Oracle Linux with Convert2RHEL

This is the Oracle Linux companion to my CentOS conversion walkthrough. I introduce Convert2RHEL and demo an in-place conversion of a vanilla Oracle Linux system to fully supported Red Hat Enterprise Linux. The process mirrors the CentOS one, with one important twist specific to Oracle.

A few things worth carrying away from this one:

• Get off the Unbreakable kernel first. An Oracle Linux conversion requires you to be running the Red Hat-compiled kernel rather than Oracle’s Unbreakable kernel before you start. Update your packages and switch kernels, then convert.
• It’s the same light-touch process. Convert2RHEL inventories your packages, subscribes the system, and swaps Oracle-signed RPMs for Red Hat-signed ones. One reboot and you’re on RHEL with the Red Hat kernel.
• You keep your work. No redeploying apps, recreating users, or rebuilding configs, plus snapshotting gives you a safe recovery path if anything goes wrong.

If you’re on Oracle Linux and eyeing a move, this shows just how manageable that path really is.
