You can upgrade vSphere Storage Appliance and VSA cluster components from verison 1.x to version 5.5 or later.

The single vSphere Storage Appliance upgrade procedure upgrades VSA Manager, the VSA cluster service, and the VSA cluster. When you upgrade vSphere Storage Appliance that is installed on the vCenter Server computer, you can first upgrade vCenter Server to a compatible version. You can also upgrade ESXi hosts that are the VSA cluster members. For information on upgrading vCenter Server and ESXi, see the vSphere Installation and Setup documentation.

A successful upgrade ensures that all appliances are upgraded from version 1.x to 5.5. You cannot use VSA appliances version 1.x with VSA Manager 5.5.

The following upgrade procedure is a full upgrade of vCenter Server, vSphere Storage Appliance and ESXi.


  • Back up all virtual machines that run on the VSA cluster on media other than the VSA cluster components.
  • Verify that the VSA cluster, including all appliances and datastores, is online and functioning properly.


  1. Upgrade the vSphere Storage Appliance components to version 5.5.
    1. On the vCenter Server machine, start the VMware-vsamanager-all-version_number-build_number.exe file.
    2. Follow the prompts to perform the upgrade.
  2. If you use a two-node VSA cluster, update the configuration file of the VSA cluster service.
    Perform this step only if you have upgraded vCenter Server from version 5.x to 5.5.
    1. Browse to the file at the following location:
      C:\Program Files\VMware\Infrastructure\VSA Manager\VSAClusterService\conf\wrapper.conf
    2. Replace the following value: Files/VMware/Infrastructure/jre/bin/java

      with the new value: Files/Common Files/VMware/VMware vCenter Server - Java Components/bin/java

  3. (Optional) Upgrade vCenter Server to a compatible version.
  4. Place the VSA cluster into cluster maintenance mode.
  5. (Optional) Upgrade ESXi hosts to a compatible version.
  6. Take the VSA cluster out of maintenance mode.

What to do next

If the VSA Manager page is disabled after the upgrade, restart VMware VirtualCenter Management Webservices. For information, see VSA Manager Page Does Not Appear.
