      In this PR I added the possibility for a cluster admin to skip the 2-phase 4.13->4.14 upgrade to OVN IC if ever things go wrong. I added a troubleshooting section in the enhancement with a couple of diagrams that explain what the user can do in such case: https://github.com/openshift/enhancements/pull/1567
      It is to be decided whether the documentation for this should be available only to support engineers or also to customers.

    • In Progress

      If ever a cluster is not making progress during phase 1 or phase 2 of the upgrade to OVN IC, a cluster admin should be able to bypass the two-phase upgrade and let CNO apply directly the multizone YAMLs.

      This applies only to upgrades from 4.13 to 4.14, due to the change in architecture in the deployed ovn-kubernetes. Any other upgrades are not affected.
