A new version of the EL8 operating system to AlmaLinux conversion script is available. This update addresses 4 issues.

almalinux-deploy

An EL to AlmaLinux migration tool.

Usage

In order to convert your EL8 operating system to AlmaLinux do the following:

1. Make a backup of the system. We didn't test all possible scenarios so there is a risk that something goes wrong. In such a situation you will have a restore point.
2. Disable Secure Boot because AlmaLinux doesn't support it yet ( almbz#3). Detailed instructions for bare metal hardware can be found  here. Instructions for VMWare are available  here.
3. Download the  almalinux-deploy.sh script:

   $ curl -O  https://raw.githubusercontent.com/AlmaLinux/almalinux-deploy/master/almalinux-deploy.sh

4. Run the script and check its output for errors:

   $ sudo bash almalinux-deploy.sh
     ...
     Migration to AlmaLinux is completed

5. Ensure that your system was successfully converted:

   # check release file
   $ cat /etc/redhat-release 
   AlmaLinux release 8.3 (Purple Manul)
   
   # check that the system boots AlmaLinux kernel by default
   $ sudo grubby --info DEFAULT | grep AlmaLinux
   title="AlmaLinux (4.18.0-240.el8.x86_64) 8"

6. Thank you for choosing AlmaLinux!
