Well, the updates are under way! the hard ones have been completed with a couple of system rebuilds. The OS chosen for this operation is AlmaLinux. It is binary compatible with RedHat/CentOS and supported by CloudLinux.
The hardest being the webserver. That machine was on CentOS 7. There is no clear and supported upgrade path from 7 to 8 and obviously, no path from 8 to Alma. That sever was a complete rebuild done with many, many rebuilds as things changed or I messed up or I added stuff that was not needed. What ever it is done.
Additional servers will be migrating soon but the core services were needed to be completed first.
