You can use the updateoffline.hzn script to perform an offline upgrade of the VMware Identity Manager virtual appliance to 3.3.7. Download the offline upgrade package from the VMware Identity Manager product download page to use with the script.
The script verifies that the upgrade package matches the product. For example, if you are upgrading the VMware Identity Manager service virtual appliance and you use the connector upgrade package instead of the service upgrade package, the script results in an error.
