RedHat announced a while back that someone with a free developer account can run up to 16 subscriptions (https://developers.redhat.com/articles/faqs-no-cost-red-hat-enterprise-linux#general). After there had been the announcement that CentOS would become an upstream OS to RHEL, we had been looking to move to Oracle Linux or Rocky Linux. Both of these are very good, and in the end I had worked a bit more with Oracle Linux.
I am now moving my Oracle Linux instances to RedHat 9. RedHat has incorporated some items into their OS that make it a bit more interesting. The addition of kpatch, which Oracle has as a subscription only feature, was one that stands out. The updates to cockpit is nice as well, where you can make it easy to make some basic configurations, and get a quick view of server status, and the ability to perform podman and some vm functions.
Migrating data between Centos and Oracle Linux is no different than moving between any other Linux based OS. The biggest challenge are the apps that are not bundled and verifying that they install correctly and function right on the new OS.
I’m excited to move in this direction and may have some updates on where this leads in the future.
