@itmnetworks nice to meet you. Respectfully, do not accept my answer is authoritative; however, with my experience dealing with CentOS since major version 5 and every other major version including 8 and the fact this is a forked project from CentOS (for historical reference)…
You cannot upgrade from one major version to the next major version. I learned this statement is true for each and every major version of CentOS, because I would ask each major version so that I had my expectations set for me and so too my understanding of the philosophy in various design aspects.
So, to familiarize yourself with AlmaLinux 8.x, you need to install AlmaLinux 8.x.
I would love to know if my understanding of the philosophy in design of CentOS is being followed with AlmaLinux as well.
Let’s see what they come back with.
