To successfully upgrade VMware Cloud Director Availability, take snapshots of all the appliances and upgrade each appliance according to a specific order.

Upgrade the sites running VMware Cloud Director Availability in the following order:
  1. In the local cloud site, upgrade all the cloud VMware Cloud Director Availability appliances.
  2. In remote cloud sites, upgrade all the cloud VMware Cloud Director Availability appliances.
  3. Upgrade all the VMware Cloud Director Availability On-Premises Appliance instances.
In a VMware Cloud Director Availability cloud site, upgrade all the appliances according to the following procedure:

Prerequisites

Important:
  • Verify that before starting the upgrade, current snapshots of all the appliances exist in the site. Take snapshots only with all the VMware Cloud Director Availability services stopped or with the appliances powered off.
  • Verify that before starting the upgrade, 60% free disk space, or more exists on all the appliances in the site.
  • Verify that the sites are prepared for replication interruptions and Recovery Point Objective (RPO) violations.

Procedure

  1. Power off the Cloud Tunnel Appliance and all Cloud Replicator Appliance instances running in the local cloud site.
  2. Upgrade the Cloud Replication Management Appliance and after a successful upgrade, power off the appliance.

    If the Cloud Replication Management Appliance upgrade fails, revert to the latest snapshot.

  3. Power on a single Cloud Replicator Appliance instance.
    1. Upgrade the Cloud Replicator Appliance instance.
    2. After a successful upgrade, power off the upgraded Cloud Replicator Appliance instance.

      If the upgrade of a Cloud Replicator Appliance instance fails, revert to the latest snapshot.

    3. Repeat this step for all the remaining Cloud Replicator Appliance instances in the local cloud site.
  4. Power on the Cloud Tunnel Appliance.
    1. Upgrade the Cloud Tunnel Appliance.
    2. After a successful upgrade, power on the upgraded Cloud Replication Management Appliance and all the upgraded Cloud Replicator Appliance instances.

      If the Cloud Tunnel Appliance upgrade fails, revert to the latest snapshot.

    All the VMware Cloud Director Availability appliances in the local cloud site are upgraded and powered on.
  5. Delete all snapshots.
    Note: Any other snapshot operation except the ones described in the first prerequisite and in steps: 2, 3b, 4b, and 5 is not supported and can potentially break VMware Cloud Director Availability.

Results

The VMware Cloud Director Availability in the local cloud site is successfully upgraded.

What to do next

After upgrading the local cloud site, the remote cloud sites, and upgrading the VMware Cloud Director Availability On-Premises Appliance instances, you can start using the new VMware Cloud Director Availability version.
