AlmaLinux vs CloudLinux 8 and migrating from CloudLinux 6.10
Shortest version I can put this:
I have dedicated servers that I run my small shared hosting business with, and I'm in a situation where I must get new servers at a new data center, and migrate all of my existing cPanel customers over to them.
Slight conundrum:
Current older servers are running WHM/cPanel 110.0.x / CloudLinux 6.10.0 on ELS , mySQL 5.7 , PHP 7.4 , along with the full CSF/LFD/Mailscanner package.
The new data center I'm considering only offers Almalinux 8.x on new provisioned boxes.
I've read that going with CloudLinux 8.x is the best way to go for busy dedicated boxes running a shared hosting environment, but I've also read that people have run into problems when trying to change from Almalinux to CloudLinux after a server has already been provisioned.
I also have my current / older servers in a WHM DNS Cluster and use my own DNS / nameservers.
Also, the new data center I'm considering is suggesting their "managed" WHM/cPanel dedicated server solutions as opposed to "bare metal" , which is appealing to me as I'm getting older and it's more difficult every day to stay on top of things / non-stop management of every little thing.
So I'm wondering (from anyone with any experience on this) - should I order the new servers as "managed" and under the new DC's Almalinux 8, and then attempt have CloudLinux 8.x installed? Can AlmaLinux alone handle the load balancing and other facets that make CloudLinux a superior choice for running a shared hosting environment with WHM DNS Clustered boxes be a sufficient way to go without reducing the security and stability of the protections that CloudLinux provides?
I will of course reach out to CloudLinux directly for their input, but I would really really like to hear some "real world experiences" from others here.
Thanks for any replies!

I can't comment on the "managed" piece, as I would have no idea of what that really includes/benefits etc.
We have not had any issues installing Alma V8 and then converting to CL. We do that conversion before there are any accounts on the server and there are numerous things that we need to do before there are acocunts.
IMHO the biggest risk your going to run into is MySQL V5.7 to MySQL V8.x. We've had zero issues with WordPress sites, but we've had issues with older (supported) versions of Drupal. Hand coded/custom sites are always iffy.My 2 cents for you.

I also am not aware of any issues with the conversion process from Alma -> CL. That's exactly what CloudLinux is designed to do, so it would be surprising to me if you ran into problems with that portion of the work.

Thank you both for the replies! I did think it was odd that I saw some people mentioning issues when switching-up, since since Alma was developed by CL. I'm going to get the new boxes with Alma and convert to CL and see how it goes, because after more reading today it is clear that CL is superior for running a shared hosting environment / protecting users.

ffeingol - Indeed I will likely have a few clients that have older scripts that won't work on mySQL 8. All I can do for them is give them some notice so they can get with a host that still has 5.7 , as I can't hold everyone else (nor myself) back any longer.
Thanks again for your input!

I have just done what you are planning to do.
MySQL was an issue for one site only. A custom system but the developer was able to fix the queries (they were backward compatible) before we moved him.
Also check if the managed service will permit you to install/use the config server scripts.

Damian - thank you for adding your input! Thankfully the new data center I'm using is familiar with CSF/LFD and even provides the bare-bones basic CSF by default with the server provisions. But if they hadn't, of course your reminder would be something I'd need!
