Unable to get into Nest account- My email Changed

[VKLA]

Rats!  I tried turning on my thermostat from the app as usual and got the Goggle migration prompt.  Low and behold, I can’t migrate as the verification code is sent to an email I no longer can access. I have both the thermostat AND several Nest smoke detectors. 
What action should I take to gain access to these devices again?  

Thanks!

Hi VKLA, 

Uh-oh! If you can no longer access the email address where the account migration verification code is being sent, you have to create a new account so you can continue migrating your devices from your Nest app to the Home app. With that being said, reset all your Nest devices added to the Nest app, then remove them from the app. Create a new Nest account, then migrate the new account to the Home app.

Let us know if that helps.

Best,

Zoe
