We've just moved and have a new Wi-Fi router, wifi name and password,  with a different provider. 

I'm trying to set up our speakers on the Wi-Fi network in the new place and as far as I can see, the only way to do that is by doing a factory reset on all of the speakers (we have 5 speakers) which seems to means  losing all of our Sonos playlists. 

Is there any way to set it up again on the new Wi-Fi, without loosing all of our playlists? 

It seems like a pretty major flaw to have to do a factory reset and loose years of playlists just to set it up in our new house. 

Thanks!
