Katello supports upgrades from version 2.0. For users transitioning from 1.4, please see - Transition Guide.
Before you upgrade, you need to run the upgrade check script that will check for any active tasks, your version of Katello, and if there are any content hosts that will be deleted (see below). This script is included in Katello 2.4.3.
To run the script:
If Katello is running on a Virtual Machine, we recommend to take a snapshot prior to upgrading. Otherwise, take a backup of the relevant databases by following the instructions here.
Ensure your operating system is fully up-to-date:
NOTE: If kernel packages are updated here (e.g. upgrading el 6.6 to 6.7), you must reboot and ensure the new kernel and SELinux policy is loaded before upgrading Katello.

The installer with the –upgrade flag will run the right database migrations for all component services, as well as adjusting the configuration to reflect what’s new in Katello 3.2
