We have the opportunity to buy a couple of Sonos units (Sones One and Playbar) installed in the office of a bankrupt company. We will move soon in the office and I would be interested to buy this installation. My concern though is to take control of this installation and attach it to an account we would create for this occasion.

The previous owner has vanished somewhere on the planet and it is impossible to get presumably actual account on this system.

The question is simple : is it possible to reassign this system to an new account without the credentials of the actual one?
