Katello 3.11 Documentation

Katello Upgrade

Katello supports upgrades from version 2.0. For users transitioning from 1.4, please see - Transition Guide.

Pre-upgrade considerations

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:

foreman-rake katello:upgrade_check

Step 1 - Backup

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.

Step 2 - Operating System

Ensure your operating system is fully up-to-date:

yum -y update

Step 3 - Repositories

Update the Foreman and Katello release packages:

  • RHEL7 / CentOS 7:
  yum update -y https://fedorapeople.org/groups/katello/releases/yum/3.11/katello/el7/x86_64/katello-repos-latest.rpm
  yum update -y https://yum.theforeman.org/releases/1.21/el7/x86_64/foreman-release.rpm
  yum update -y foreman-release-scl

Step 4 - Update Packages

Clean the yum cache

yum clean all

Update the required packages:

yum -y update

Step 5 - Run Installer

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 3.11

foreman-installer --scenario katello --upgrade

Step 6 - Reboot if necessary

If kernel packages are updated during Step 2 (e.g. upgrading el 6.6 to 6.7), you must reboot and ensure the new kernel and SELinux policy are loaded. If there are no kernel or selinux updates then this step can be omitted.
