Upgrade your CentOS Stream 8 virtual machine or migrate it to either Rocky Linux or AlmaLinux

Now that CentOS Stream 8 has reached EOL on May 31, 2024, is there a way to upgrade to CentOS Stream 9?

We were not able to find any official upgrade instructions.

Unofficially, there is this 3rd party guide that documents the live upgrade steps to CentOS Stream 9.

As an alternative, you may consider to:

  1. Live migration to Rocky Linux 8, or
  2. Live migration to AlmaLinux 8.

Both Rocky Linux and AlmaLinux are open-source enterprise operating system designed to be compatible with Red Hat Enterprise Linux, and therefore are a very good alternative to CentOS Stream 8.

One or more virtual machine reboots are required during the upgrade or migration procedures listed above.

IMPORTANT: As with any live upgrade, it is very important to prepare well. Make sure you test in advance the upgrade procedure using a test virtual machine. Also, make sure you back up all your data before performing the actual upgrade. PROCOMPUTERS SHALL NOT BE HELD LIABLE FOR ANY LOSS, DAMAGE, OR DISRUPTION RESULTING FROM THE UPGRADE PROCESS. THIS INCLUDES, BUT IS NOT LIMITED TO, DATA LOSS, SERVICE INTERRUPTIONS, OR ANY OTHER ADVERSE EFFECTS THAT MAY ARISE.
