As we know CentOS 7 will be EOL in June the 24th. I currently have 7.9 core installed in my network, however because of the EOL and other security risks I was wondering what my best option would be. Therefore I would like to have your guys opinion on this.
Should i:
Migrate to the latest centos version c9s? (Complete reinstall?)
something else?
I think it depends a lot on your environment, acceptable risk, sw you running, familarity with OS and so. I'm in a similar position, need to migrate to something else. On some less important system I moved on to Centos stream and some are now on Rocky. Since I'm running ubuntu at work I moved to ubuntu 22.04 LTS on some. Was going for Debian for my backup server but hit a snag with that to run bacula on debian I have to cmpile from source if I want dedup to work.
Upgrade is often easier than complete reinstall but reinstall is also a good time to look for upgrading the sw to use. If you go with upgrade or rolling upgrade you may end up with a pile of old software that is no longer used but still hang around.
So, without knowing more about your environment no one but you can figure out the best route.
