You can install vCloud Usage Meter 4.3 as an in-place upgrade on top of vCloud Usage Meter 4.x or as a new appliance on top of vCloud Usage Meter 3.6.x. After you deploy the vCloud Usage Meter 4.3 appliance, you can optionally migrate the product configuration data from the source vCloud Usage Meter appliance to the target vCloud Usage Meter 4.3 appliance.

If you migrate from vCloud Usage Meter 3.6.x, you must accept the legal agreement that is displayed after you complete the migration to vCloud Usage Meter 4.3.

If you want to run in parallel both old and new appliances for a full reporting period, in Commerce Portal, set the vCloud Usage Meter 4.3 instance to Test mode. The product consumption data from the vCloud Usage Meter 4.3 instances is still collected, aggregated, and made available for reference to you.

Then if you want to enable vCloud Usage Meter 4.3 for reporting, in Commerce Portal, update the mode of the vCloud Usage Meter 4.3 instance from Test to Production, and 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.

To upgrade the vCloud Usage Meter appliance, you must install only the official vCloud Usage Meter updates provided by VMware.
