App Transfer And push FireBase cloud messaging

hello

I'd like to transfer my application to another Apple dev account in the near future, my application uses FireBase cloud messaging to receive notifications

What exactly should I do once the transfer is done?

Should I just update the APNs authentication key on the FireBase console in Project parameters ? Should I also change the team ID on the fireBase console ?

Does this mean generating a new GoogleService-Info.plist file and therefore an application update ?
