Google Begins Rolling Out Long-Awaited @gmail.com Email Feature to Users 

Google is rolling out a feature that lets users change their primary @gmail.com address to another @gmail.com while preserving access to all Google Account data and services; emails are redirected during a transition period and users can sign in with either address. The update includes restrictions (e.g., 12-month reuse limits and non-deletable new address), advises reviewing potential issues with Chromebooks, Sign-in with Google, and Chrome Remote Desktop, recommends backing up data, and provides steps to initiate the change via myaccount.google.com.
