Google Begins Rolling Out Option to Change Primary Gmail Address Without Data Loss

Google’s support pages say the old address becomes an alias that still works for sign‑in.

Overview

Users can switch to a new @gmail.com address while keeping emails, photos, and other account data intact.
After the change, the previous Gmail address is set as an alias, and either address can be used to access Google services.
The rollout is gradual, so the setting may not appear for everyone yet or on all devices.
Google limits how often you can change the address, blocking another new address for 12 months, while the old address can be reused.
Google recommends backing up data first because some app settings may reset, and availability can be checked under Google Account > Personal info > Email.
