For a complete upgrade operation, follow these steps:

  1. Configure a backup before upgrading the cluster to a new version, if possible.
  2. Enable maintenance mode on the cluster, by bringing down the cluster network, to avoid any writes during upgrade. This step ensures the upgrade is consistent.
  3. Upgrade Kubernetes and other infrastructure components on all the cluster nodes.
  4. For offline installations, hydrate Private Docker Registry with the new container images.
  5. Upgrade the fabric and shared components on the cluster.
  6. Upgrade the services.
  7. Bring back the cluster by disabling the maintenance mode on the cluster.
