This is a very important milestone for us since we have a lot of Centos 7 servers and can't go to RHEL. From my point of view, there are more or less three solutions:
a. Go to Debian (or ubuntu server etc); probably the most difficult since everything will be different
b. Go to a fresh Almalinux or Rocky 9 installation; also very difficult since there's a lot of stuff to be moved
c. Try to use in-place upgrade using Leapp or something. There are some guides for this (https://wiki.almalinux.org/elevate/ELevating-CentOS7-to-Alma...) but I'm really not sure how good this would work on a live production system.
I'd definitely prefer the solution c, if I can confirm that it works of course. Has anybody tried using leapp to upgrade Centos 7 to Rocky/Alma ? What was your experience? Do you feel that it's worth researching that path or it's probably better to move to a greenfield installation?
