Question Conversion of Centos 8 server with Plesk to Almalinux ?

[JulianDot]

I saw in Changelog for 18.0.37 : Change Log for Plesk Obsidian

Converting a CentOS server with Plesk to AlmaLinux no longer fails if the EPEL repository is enabled on the server. (PPP-53540)

That mean I can try to convert a Centos 8 server with Plesk to Almalinux ?

Thanks

Hmm, it seem is working , the in-place conversion from Centos 8 with Plesk to Almalinux 8.4 with Plesk

No major issues (yet)

Which tutorial did you use? I want to wait a little longer, but I would be interested to know who in Plesk has successfully switched to AlmaLinux and with what steps.

1. Be sure your current Centos Plesk is up to date
2. disable in Plesk SystemUpdates-> Automatically install system package updates
3. follow this tutorial Migrate To AlmaLinux From CentOS 8 Using Almalinux-deploy Script - OSTechNix
4. after reboot, enable SystemUpdates-> Automatically install system package updates

Thanks you!
I had found this tutorial: How to migrate from CentOS to AlmaLinux - LinuxConfig.org
I will remember both of them. Thanks for the hint with the "SystemUpdate".

Who is already using AlmaLinux and are there any problems with it?

Hi,
there is no difference in operation between centos 8 + Plesk and Almalinux + Plesk

as described here:

for me that was not the case as i had already excluded the awstats from epel but it is worth a look:

@moswak Can you tell me how long the script took to switch from CentOS to AlmaLinux? (in your case)

that was a few weeks ago and I don't know exactly anymore. but it was always only a few minutes.

I was VERY anxious. I tried to update one of our servers. Of course backup, snapshot etc. before updating.

In my case after I updated CentOS to latest release (8.5) and after I ensured my Plesk is up to date - I followed this tutorial:

How to migrate from CentOS to AlmaLinux

In this tutorial, we show the step by step instructions to migrate seamlessly from CentOS Linux to AlmaLinux.

linuxconfig.org

It updated itself to AlmaLinux - process was around 9 minutes. Everything seems to be working perfectly. No issues whatsoever. It simply works. Server seems smooth, Plesk working nice. Actually I think I am going crazy but Plesk seems snappier and more responsive.

 

[Azurel]

Same here. No errors and all working fine.

No issues so far with Plesk on Almalinux, no worries, it's rebranded fork of RHEL/CentOS with open source privileges.

After CentOS burnout I was very skeptical about the whole thing, but it really seems to be working with no issues whatsoever.

Since it's running only a day It is probably too early to say it's safe completely, but posts like yours and from the people above are really encouraging.

Happy new year everyone!

Migrated a dozen Centos 8 Plesk Servers this week to AlmaLinux ... so far no problems with the Migration ... all running as expected!

On 2 or 3 of our Plesk Server's the Migration Script failed as it failed to move one of the old dnf repos:
Error:
