SUMMARY
Moving a Cloud Backup Data Store from one VBA to another
ISSUE
To re-use an existing cloud backup data store with a new Virtual Backup Appliance you must first remove the data store from the initial VBA. This is accomplished by setting the VBA's Backup Storage to None then rebooting the VBA.
After the VBA reboots you can then configure the new VBA's Backup Storage to use the previous VBA's cloud data store.
