Actually I am afraid I have to differ. Most z-wave mains powered devices do have a factory reset procedure for exactly this reason. Problems can occur when a ghost device is left on an old hub - with that hub. Resetting the device and including in a new mesh is entirely approriate if there are problems in exclusion.
Mike Maxwell has recommended this on several occasions and I certainly found this useful when transferring from older hubs. On what basis do you state "this is bad information"?
