  • Check if any upgrade warnings exist
    • 12.1 changes related to monitoring do not apply to this demo.
    • 12.2 number of unicorn workers is calculated differently, but not important.
  • Make sure you have access to Geoffrey - The happy HA Geo cluster
  • Verify that the Geo cluster is healthy pre upgrade
    • Verify all versions match
    • Manually double check /etc/gitlab/gitlab.rb on each machine
  • Find the latest packaged version of GitLab that can be used for zero downtime upgrades
