It is crazy how difficult it is for the Sonos to change wifi. I tried 20 times following the Sonos process and nothing worked. In the end the only way I could change the Sonos wifi was to (its ridiculous that this is necessary but anyway)
Factory reset the sonos
Uninstall and install the Sonos app on my phone
There has to be an easier way for this to work, but for the life of me I nothing else would.
Any comments from the Sonos team?
Oh yeah and I also bought the Sonos one almost 2 years ago thinking I was gonna be able to use Google assistant, but this still hasn't happened.
Too be honest I'm not very happy with my purchase...

Just cable a Sonos device to the router at the new location and then power on any other speakers (if you have taken more than one with you) ... connect your mobile to the same routers WiFi signal and away you go... Job done!
If you then decide that you don’t want to leave the initial speaker cabled to the router and prefer to run all speakers on the new WiFi ... just change the wife credentials in Advanced/Settings/Wireless Setup of the Sonos App.
No need to factory reset or uninstall anything at all.
I regularly take two of my Sonos One speakers to my Son's house, when they have a garden party for family and friends.
It’s really a very easy/simple process, er...when you understand what you are doing and know how everything works.
The only difficult bit, is remembering to take the Ethernet cable that Sonos provide free with a majority of their products, as my son can never (ever) find the ones I have left at his house on previous occasions.
