vCloud Usage Meter 3.6.0.1 is installed as a new appliance. After you install and configure the vCloud Usage Meter 3.6.0.1 appliance, you can optionally migrate data from vCloud Usage Meter 3.5.0.0 and 3.6.0.0.

To upgrade to vCloud Usage Meter 3.6.0.1, you can deploy and configure a new appliance. Alternatively, you can deploy a new vCloud Usage Meter 3.6.0.1 appliance and migrate configuration and collected consumption data from your vCloud Usage Meter 3.5.0.0 or 3.6.0.0 appliance.

Regardless if you migrated data, or deployed and configured a new appliance, run both vCloud Usage Meter appliances for at least two months. Use the vCloud Usage Meter 3.6.0.1 for reporting. Then shut down and backup the old vCloud Usage Meter appliance.

VMware Cloud Provider Program stipulates that Service Providers keep the product consumption data for 24 months going back from the current month.
