Ensure that the following prerequisites are met before starting an update.

  1. Take a backup of the SDDC Manager VM. This is required since the SDDC Manager VM will be rebooted during the update.
  2. Take a snapshot of relevant VMs in your management domain.
  3. Do not run any domain operations while an update is in progress. Domain operations are creating a new VI domain, adding hosts to a cluster or adding a cluster to a workload domain, and removing clusters or hosts from a workload domain.
  4. You must have downloaded the relevant bundles. See Download Bundles.
  5. Ensure that there are no failed workflows in your system and none of the Cloud Foundation resources are in activating or error state. If any of these conditions are true, contact VMware Support before starting the update.
  6. Confirm that the passwords for all Cloud Foundation components are valid.
