I may have some work converting CentOS 7 up to something current and thinking about which distro to go with. Leaning towards Alma because they made the tool to make this “easy” and also because XCP-ng is going to base their next (v9) on Alma 10 (hard to find forum post).
My system may have a support contract with Oracle, and that might twist me in that direction, but I’m trying to avoid it because the Alma conversion tool only goes up to Oracle v8, where the tool can get you up to Alma v9 or Rocky v9 (with a trip to 8 first).
We may also contract this out, the VP is talking to HR to see if they can pay me without breaking any labor laws since I work for this company in a different role. I’ll assume that CNWR has done more than a few of these upgrades by now, not aware of any other companies closer to us, and not really sure close matters for this.
We’re primarily a Debian shop, but had a single CentOS VM that we converted to Alma a couple years ago, apparently (I had to go back and look up when the whole CentOS shake-up happened) and everything has been pretty smooth. The conversion script was as boring as one might hope and the legacy software that we need that VM for hasn’t complained.
Yeah, I’ve mainly gone to Debian after the IBM rug pull, but I think we still have many CentOS7, and not sure what state our RHEL might be in. If everything is a VM, then not a big deal, make a snap shot to fall back on, and let it rip. And I’m guessing most are a VM, but I think there are a couple of unknown bare metal machines that need attention.
I may shift my few Linux VMs on my system over to Alma just for practice. I can burn them down and start fresh so not a big deal for my little system. Need to see what happens with this work.
