How To Migrate
The minimal supported version of EL8 operating systems is 8.4. In case your OS version is lower, please, upgrade it.
NOTE: It’s recommended to have a backup or snapshot of your system. There’ll be a restore point if something will go wrong.
Follow these steps to convert your EL8 or EL9 system to AlmaLinux using CLI:
- Run the following command to update your operating system if needed:
sudo dnf update -y
- Run the following command to download almalinux-deploy.sh script:
curl -O https://raw.githubusercontent.com/AlmaLinux/almalinux-deploy/master/almalinux-deploy.sh
- Run the script:
sudo bash almalinux-deploy.sh
Check the output for any errors. If the conversion went without any issues, you’ll see that Migration to AlmaLinux is completed in the output.
- Reboot the system to boot with AlmaLinux kernel:
sudo reboot
- Ensure that your system was successfully converted:
cat /etc/redhat-release
You should see: AlmaLinux release 8.7 (Stone Smilodon)
- Check that the system boots with AlmaLinux kernel by default:
sudo grubby --info DEFAULT | grep AlmaLinux
You should see something like:
title="AlmaLinux (4.18.0-425.3.1.el8.x86_64) 8.7 (Stone Smilodon)"
Thanks for learning with Starburst Services.
