Yes, but this all depends if you have any ‘other’ Sonos products?
Assuming you do have other devices… then, unbond/remove any surrounds & Sub and it’s often helpful, but optional, to rename the old Playbase ‘room’ to something different. Then if practical, factory reset the old Playbase product (if necessary) ready to sell, or recycle etc. Don’t do this though if you intend to keep it and use it elsewhere in the home (important).
Next, it’s a good idea to fully close the Sonos app and to power off all your Sonos devices and then bring them back online one at a time, that helps the setup to forget the old Playbase. If it does ever show up again, then just see if the App lets you hide it.
Next, open the Sonos App to see all your other Sonos devices and then power on your new Playbase and add it to your system via ‘Settings/System/Add Product’. Give it the same original name as your old Playbase and then setup the remote control using ‘Settings/System/[Playbase Name]/TV Remote’ and also add any surrounds and Sub to it, same as before, if required.
If you do not have any other Sonos devices, then you are best to take a slightly different route and this will also depend if your old Playbase is still functioning, or not. So just post back if that’s the case.
