Removing older Sonos product from S2 without resetting it

Greetings, 

I recently bought a new Sonos Beam which prompted me to finally upgrade my system to S2. I now only have one device, a Play 5, that is not compatible with S2. The Play 5 is in my office so I’m fine with keeping it on S1 and not using it in conjunction with anything else. The trouble is the S2 app keeps telling me I have an incompatible product and I can’t upgrade anything until I delete it from the S2 system. I understand that resetting the Play 5 will remove it but am wondering if there’s a less drastic way to do it, as I have a ton of music services, playlists, etc. associated with it that I’m not relishing recreating. Any help would be appreciated. Thanks.
