      NOTE: this guide exists for Upgrading from v3.11 to v3.12 as well -->  here Additionally, ensure the successful completion of the upgrade/migration to an EL9 host.

Foreman has supported el9 for several releases. With Foreman 3.12 and Katello 4.14 being the last supported versions on el8, it's time to upgrade. Upgrading to el9 will provide access to future upgrades, streamline the verisons used in my infrastructure and the latest security and performance improvements. I'll be upgrading my Server using leapp again just like I did previously. The procedure is outlined quite well in the documentation but here's my own take on documenting the procedure. NOTE: before continuing, please ensure you have a way to roll back any changes in case anything goes wrong. First, apply the latest patches for all packages: [root@katello01 ~]# dnf -4y --refresh update Check if a reboot is required: [root@katello01 ~]# dnf needs-restarting -r Perform a reboot if system libraries and packages have been upgraded: [root@katello01 ~]# systemctl reboot Once the server is back online, we can begin with the upgrade. To facilitate the transition from EL8 ...
