You can upgrade from vCenter Server Appliance 5.1 Update 3 and 5.5.x to 6.0.

The upgrade process includes:

  1. Exporting the vCenter Server Appliance 5.1 Update 3 or 5.5.x configuration.

  2. Deploying the vCenter Server Appliance 6.0.

  3. Migrating the vCenter Server Appliance 5.1 Update 3 or 5.5.x services and configuration data to the new vCenter Server Appliance 6.0 deployment.

    Non-ephemeral distributed virtual port groups are not migrated. After the upgrade, you can manually connect the new appliance to a non-ephemeral distributed virtual port group.

  4. Powering off the vCenter Server Appliance 5.1 Update 3 or 5.5.x machine that you want to upgrade.

Note:

Upgrade of vCenter Server Appliance that is registered with an external vCenter Single Sign-On server is supported only for vCenter Server Appliance 5.5.x.

If your current vCenter Server Appliance version is earlier than 5.1 Update 3, you must upgrade to 5.1 Update 3 or later before upgrading to vCenter Server Appliance 6.0.

If you have multiple instances of vCenter Server Appliance, concurrent upgrades are not supported. You must upgrade one instance at a time.
