AlmaLinux Is There An Upgrade Document Centos to Almalinux?

CentOS 7 End Of Life

Quick Summary:

CentOS 7 is end of life meaning no more security or bug fix updates provided by official YUM repositories. To migrate you need to create a new server with either AlmaLinux 8/9 or Rocky Linux 8/9 and install Centmin Mod 131.00stable or 140.00beta01 on the new server. And then migrate your CentOS 7 server data to the new Centmin Mod 131.00stable or 140.00beta01 install AlmaLinux or Rocky Linux server.

Details:

With CentOS 7's end-of-life date of June 30, 2024, security and software updates will stop. But the server will still operate. The options for migration are to set up a new server and install recently released Centmin Mod 131.00stable or 140.00beta01 or newer on a EL8-based Linux distribution operating systems: AlmaLinux 8 or Rocky Linux 8 (recommended for most folks) and then migrate and move your data from CentOS 7 server to AlmaLinux 8 or Rocky Linux 8 based server. Example AlmaLinux 8 install of Centmin Mod 130.00beta01 on DigitalOcean droplet VPS server - 130.00beta01 install will be same as 131.00stable or 140.00beta01.

Most of the Centmin Mod beta testing has been focused on EL8 but EL9 based AlmaLinux 9 or Rocky Linux 9 has been concurrently tested but not to the extend of EL8.

You have a few choices right now for data migration from CentOS 7 to EL8 or EL9 based servers:

1. First is https://community.centminmod.com/threads/centmin-mod-site-data-migration-guide.10382/, which outlines Centmin Mod to Centmin Mod data transfers using tools and techniques that apply to any server move. This migration process I've been doing for decades, and the basic underlying tools and what they are used for are always the same
2. Or Centmin Mod revamped centmin.sh menu option 21 data management menu which I've been developing/testing/using already for migrations to EL8/EL9. It uses the fastest method for data transfers available from my years of experience There are both shell menu and shell script command line options available. You can do test migrations without updating domain(s) DNS just to practice and get familiar with the process. The centmin.sh menu option 21 is designed so you could in fact do multiple data transfers to the same server or different servers and each backup will be transferred to their own staging directory. So you can in fact use it like a remote backup method for whole server data as you have the shell script command line options available. There's very detailed centmin.sh menu option 21 documentation for Centmin Mod 131.00stable and Centmin Mod 140.00beta01. There are separate links as documentation will eventually diverge as Centmin Mod 140.00beta01 development continues to improve on the code.
3. Or hire someone to do the Centmin Mod migration. I've been doing a lot of Centmin Mod and non-Centmin CentOS 7 migrations to EL8/EL9 based Centmin Mod / non-Centmin Mod servers lately - using the centmin.sh menu option 21 revamped data management menu for them too
