Ahh that is interesting! Do you know is there a doc. on how that's done? Also does that mean that once the clone is done you can effectively just register once

Ahh that is interesting! Do you know is there a doc. on how that's done? Also does that mean that once the clone is done you can effectively just register once with your "live" key and if it fails seemlessly use the "backup" key or do you need to register with both for that to work?
