how can i move a speaker to another system

Before opting to reset anything - if you leave the speaker from work powered off temporarily and you put the original home speaker back to where it was (i.e. with nothing changed) do you then see that home system as before in your sonos App?

No, it no longer works at all. I can’t get the controller to open on my computer and when i try to open it on my phone it says it can’t find a system. I’ve downloaded new apps, rebooted everything, even my computer router and updated my phone. Nothing seems to work. Ive been messing around with this for 2 days 

the one im trying to set up is the gen 2 on the right. I tried to wire it directly to the home router with cable but that didn’t work either. I’ve tried both of the s1 and s2 controler on my phone. the s2 app says the speaker isn’t compatible and the s1 app says it can’t find the speaker. I tried resetting both of the speakers to factory as well. I can get to the point where there is the flashing green light and on the app i try to add a device. When i get to the poiint of pushing the button on the back it says it can’t find it  

Your community profile here mentions a Play: 3 and a Play:5 (gen1) so it’s important to be sure about the generation of the Play:5 speaker as the gen1 will not setup on the S2 App - it is S1 compatible only.

I mentioned the phone controller operating system version in my earlier post, as that is also very important as earlier versions maybe incompatible ..and perhaps more importantly the recent iOS 14.2 had/has issues with Apple WAC (Wireless Accessory Configuration) and their new ‘Private Address’ security feature, which causes problems with a sonos system setup… it’s therefore important to sort out those few things and I suspect your setup issues might then be resolved. Any recent compatible Android mobile controller should be okay.
 

So if using Apple iOS 14.2 - I would first upgrade to the latest iOS update. Wire the speaker to the router and factory reset (so the status LED flashes Green) ...and if it is a Gen1 Play:5 then use the S1 app (you are best to remove the S2 App before setup). If it’s Gen 2 then use the S2 App (you are best to remove the S1 App before setup).

Important Note: S1 devices ‘may’ now need an existing S1 system to setup any S1 factory devices so if the problems persists, then I would suggest contacting Sonos Customer Care via this LINK

OK so here is a new problem. When i originally bought the sonos i gave an email address and i now have no idea what my password might have been. That email is no longer in service as the company is now out of business. When i try to sign in to the sonos2 app it asks for the password to my old email and if i forgot it it would send the instructions to my old email account. How can i update to my new email when i can’t use the old one to get instructions 

If you have totally forgotten the password, when you factory reset the speakers and controller, it gives you the opportunity to begin from a new setup. If you are able to recall the password there is an option in ‘Settings/System’ to transfer the Sonos system to a new account/email. It depends if you can recall the password, or not?

I’ve tried all the ones that i thought it might be but nothing works, I need to set up a new account but i need to get into the old email to do that, but the old email no longer exists  

Just reset your speakers if that’s okay with yourself - I think you mentioned that you did that anyway.
 

To reset your controller - you will find that option in "Settings/App Preferences"

just tried that and it sent me the verification code which all worked but then when i try to update the system it says there is a problem and wont go any further. when i click on add a product or add your play 5 it keeps asking me for the password to my old (non existant) email account  if i try to enter the new account info that i just set up it says this email does not match our records
