Updating Sonos to latest version
Hi. I froze my Sonos system at 8.4 in order to preserve my CR100’s. I am about to buy 2 second hand ZP120’s to add to the system. I suspect that I can only link them if my entire system is running the same firmware, and the ones I am going to purchase are running the latest firmware. I’ve read that I need to do a factory reset on the new units then add them as new units. I also know that updating the existing units will brick the CR100s. The question is: What will happen to my Sonos playlists during the update process - will they be preserved?
