[Xymon] Xymon Server on RHEL9

[John Thurston]

Colin's question was related directly to NTP with RHEL 9. Mine is more 
general, but I think related enough to go here.

Our Xymon servers are running on CentOS 7. I need to look at my options 
to get those replaced (or turned into) Linux 8 or 9. Alma Linux is where 
I've taken other hosts in this situation; mostly to 9, but one to 8 due 
to package availability.

When we moved our Xymon service from Solaris to Linux, it was 
(obviously) a completely new deployment. Our current Xymon servers have 
lots of things besides Xymon running on them. There are external hosts 
pushing files in via scp through service accounts, and local cron jobs 
consuming those files to generate test results (and special Xymon web 
pages). There are customization to the apache web server handling 
authentication and delivering non-Xymon (but related) content. And other 
stuff I'm sure I've forgotten about. It's going to be whole lot of work 
to re-build all of this on a new host, and move traffic to it.

I've used 'elevate <https://almalinux.org/elevate/>' (from Red Hat's 
'Leapp') with several other systems to lift them from CentOS 7 to CentOS 
Stream 8, or Alma 8 & 9. It wasn't as simple as falling off a log, and 
it wasn't successful in all cases, but in several cases it did what it 
was supposed to do and saved us a huge amount of work.

Has anyone tried "elevating" their older Linux Xymon server to Linux 9 ?
