I’m glad you had a good experience but, she had you set up a “new” Apple account when you were upgrading? That’s not necessary at all. You just sign in with your current account and your settings, apps, purchases, etc are downloaded to the new device. They are connected to your account so if you actually set up a new account, you may be missing a lot of contacts, pictures, reminders, calendar dates, etc that you had on your previous phone.
I hope that was just mistyping as most folks with experience with the products would have made sure your data got transferred.
