Correct. The only ‘gotcha’ is Z-Wave JS UI may not be able to back up the husbzb-1 z-wave mesh. That’s what the rest of the stuff in this thread was talking about, finding a way to make the upgrade happen. You can use the Aeotec utility to back up husbzb-1 to a 500 series stick, then use z-wave js ui to back up the 500 stick to zwa-2.
