I have found Debian to be minimally different from CentOS, in all actuality; much less different than transitioning to a *BSD would be.? I've transitioned already deployed and configured production CentOS 8 machines to either Alma or Rocky (path of least resistance), keeping CentOS 7 machines on 7 until I need to revisit in 2023, and CentOS 6 machines went to Debian 10.? Now, I'm going to say that the availability of both Rocky and Alma is a very good thing, and that availability made things a lot easier for a few already deployed production systems that needed to stay stable through the end of the year. New servers are being deployed on Debian 10; new virtualization hosts on Proxmox 6.4, although I am testing the Proxmox 6 to 7 upgrade path at one site and on my development hosts at the main site.? Proxmox is SLICK.? The upgrade path for simple servers from Debian 10 to Debian 11 is relatively simple, with a few caveats (no python 2.x in 11, so no Mailman 2.x, for instance).? I have upgraded a few development servers from 10 to 11, and no issues were noted. Your mileage may vary, of course, but I've had a reasonably good experience with this transition.?? Thought I'd never say that; I've been a Red Hat user (partisan, even) for a very long time.

[CentOS] Transition test report going from CentOS8 to Debian 10.
Lamar, Were these deployed on bare metal or as virtual machines?? If Virtual were they on vmware? Can anyone else chime in on their experience with these platforms in a vmware environment?? Are there any special network card / controller card settings that have worked best? Can anyone speak to how well a virtual machine will perform when being given 1 socket 1 core, vs. 1 socket 2 cores vs 2 sockets 1 core?
