almalinux.org VS almalinux-deploy

This might be a good use case for RHEL family distribution (such as CentOS Stream or AlmaLinux) or Debian. These are much longer lived distributions, and provide fewer update churn over time than other distributions.

If If you feel more comfortable on a RHEL based distro, there a good alternatives to CentOS such as AlmaLinux or Rocky Linux.

This situation still exists and Gregory Kurtzer's RockyLinux (Greg started CentOS originally), CloudLinux's AlmaLinux, and others exist to fill the need for a freely installable RHEL clone.

If you go to https://almalinux.org and click download, then click "Get Live Media Image", you'll be sent to a page with that link as well.

Look at AlmaLinux also. I'm not sure of any technical reason why you'd chose one over the other, but AlmaLinux is a public non-profit with a board, Rocky ownership is a private org.

I moved everything to UbuntuLTS also, and I'm not moving again. But if I had waited, and I sort of wish I had, I'd probably be moving to Alma.

I was raised on Debian and I've been using it for all my Linux servers. On my ESXi I use VMware Photon OS as the host OS for my Docker. My primary client is using Alma Linux as the host OS for their Docker deployments.

Running another 8.x? Move to AlmaLinux using almalinux-deploy.

I mention that because you had to be at CentOS 8 latest, and since CentOS is now a stinkin pile of nothingness, there are adjustments path wise to point at Alma's capture of that in order to prep to make the jump. I think all that is documented here: https://github.com/AlmaLinux/almalinux-deploy

You can also convert an Oracle Cloud to Alma or Rocky then install ApisCP. If you do, append -s has_low_memory=1 to the installer.

If going with Oracle Linux it's necessary to convert to Alma or Rocky before installing the 30-day trial. This also doubles as a great hack for a free 1 GB DNS-only server.

Just follow those steps to migrate centos to almalinux: https://github.com/AlmaLinux/almalinux-deploy

I understand from here that it is recommended to update to CentOS 8.5. I have carefully inspected the recommended approaches from the README and this issue and attempted to cobble together something that I believe should work but I am facing some issues.

I used the Almalinux deploy script to switch to Alma.

A version of our Open Source hosting control panel (BlueOnyx 5210R) was initially shipped with CentOS 8 as base OS before we switched the installation media to AlmaLinux. Those that were still running CentOS 8 were informed via the GUI to convert to AlmaLinux by running the AlmaLinux conversion script that we had bundled with an update or ours.

Thanks for the questions. We already have several migration options. If you're currently on CentOS 8 or any other EL8 you can use this: https://github.com/AlmaLinux/almalinux-deploy. If you are on CentOS 7.x you can use our ELevate project: https://almalinux.org/elevate.
