This is great for those who use a silly or embarrassing address they now regret, or for people whose names or circumstances have changed. Thankfully, this will keep all your stored data completely intact. All the years of photos, Drive files, messages, and emails will not be lost just because you updated your username. That’s a massive relief because migrating years of digital life is always a nightmare.”
