NOTE: this guide exists for Upgrading from v3.12 to v3.13 as well --> here
With the current version, the official documentation is quite good and can be referenced.
I would recommend executing all of these commands in a tmux session so that your session will remain on the server in case anything happens to your workstation.
Start by checking for running tasks that would prohibit an update:
[root@katello01 ~]# foreman-rake katello:upgrade_check
Next, update the katello host and reboot if yum tells you to:
[root@katello01 ~]# dnf -4 --refresh upgrade
[root@katello01 ~]# dnf needs-restarting -r
If there were any updates to foreman-related packages, make sure foreman is in a consistent state:
[root@katello01 ~]# foreman-maintain service stop
[root@katello01 ~]# foreman-installer --scenario katello
When the katello services have started again, upgrade the release-rpms:
[root@katello01 ~]# dnf -y --refresh upgrade https://yum.theforeman.org/releases/3.14/el9/x86_64/foreman-release.rpm https://yum.theforeman.org/katello/4.16/katello/el9/x86_64/katello-repos-latest.rpm
Before updating, stop the foreman-services:
[root@katello01 ~]# foreman-maintain service stop
Update the system:
[root@katello01 ~]# dnf -y --refresh update
After the updates have completed, re-run the installer to ensure consistency:
[root@katello01 ~]# foreman-installer --scenario katello
At this point of the installation, I've encountered this issue but the fix was fairly straight forward. After resolving the issue, I was able to continue with checking the health of the installation by using these commands:
[root@katello01 ~]# foreman-maintain service list
[root@katello01 ~]# foreman-maintain service status
[root@katello01 ~]# foreman-maintain health check
Once you verified the health of your installation successfully, foreman / katello are updated to foreman version 3.14 and katello version 4.16.
