vCloud Usage Meter 3.6.1 is installed as a new appliance. After you install and configure the vCloud Usage Meter 3.6.1 appliance, you can optionally migrate data from vCloud Usage Meter 3.5.0.0, 3.6.0.0, and 3.6.0.1.

To upgrade to vCloud Usage Meter 3.6.1, you can deploy and configure a new appliance. Alternatively, you can deploy a new vCloud Usage Meter 3.6.1 appliance and migrate configuration and collected consumption data from a vCloud Usage Meter 3.5.0.0, 3.6.0.0, or 3.6.0.1 appliance.

If you are migrating from vCloud Usage Meter 3.5.0.0, you must accept the legal agreement that is displayed when you first log in to the vCloud Usage Meter Web application.

If you are migrating from vCloud Usage Meter 3.6.0.0 or 3.6.0.1 and have already accepted the legal agreement, you do not need to accept it again after you complete the migration to vCloud Usage Meter 3.6.1.

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 3.6.1 for reporting. Then shut down and back up 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.
