How to migrate CentOS 8 to AlmaLinux

AlmaLinux is an exciting new distribution, that aims to carry on CentOS (as we used to know it). In this video, I show of a migration script that can be used to migrate from CentOS8 to AlmaLinux, in place.

The process is pretty straightforward, this is awesome! Amazing content as usual Jay!

[AnzanHoshinRoshi]

Thank you, Jay. I am very impressed by the AlmaLinux devs.

Man, a lot of companies will love this. Although, I don't know anything about servers and this video made little sense to me, I just love how this looked so painless.

Superb video as always! Thank you. I'll have to check out AlmaLinux at some point since I am a big fan of CentOS 6/7/8 Linux and have taught all three when I was a college professor.

Almalinux (all my Linux), misheard but sounds cool 😁

Thanks Jay for another great video. I don’t think this script is something RHEL & IBM will be too enthusiastic about. Jumping ship is painless and with Alma linux offering a support tier via Cloud Linux... I would imagine that people will switch in droves... Saw your nice video about Alma Linux. The artwork looks fabulous! Hopefully it will run on my beloved ancient ThinkPad ☺️

Hey @jay Thanks for this tutorial, I'm a linode user, and I'm wondering if you would be able to use this deployment to then install cpanel using the marketplace script. Or would you need to install CentOS install cpanel, then use the migration script to convert the server to AlmaLinux. Now July21 there is still no current alamlinux for cpanel script. You can however choose Alamalinux as a distro. Or would you be able to create a future video of Almalinux and cpanel install on linode/digitalocean, etc. Thanks.

hostnamectl doesn't exist on alma?
It does...that is easier then editing two files.
'hostnamectl set-hostname <name>'

How do we take a snapshot manually on our own if we don't have access to it from the host provider?

Has anyone recently done this on a production server that is running a LAMP stack, that includes Litespeed?

[lsdowdle]

One thing I haven't figured out yet is... I have a local mirror of AlmaLinux setup but I can't change the dnf config to use it. I move the stock .repo files out of the way and drop in my own .repo file but dnf says it will ignore it. I do NOT get this behavior on Fedora nor CentOS when I replace the stock .repo with my own mirror one. HELP!

Hello, in the case of deciding to migrate from centOS7 to AlmaLinux, should we first upgrade to centOS8 or is there a direct step ??? Thanks

[gangadharpavan]

Hey I'm currently working as Linux Admin.... I want to shift to different technology or within which doesn't include coding at all...can you please suggest

centOS7 to AlmaLinux, issue coming regarding linode kernel

Jay, your book on Ubuntu server administration - do you cover Samba very deeply?
