Transfer Your Data to a New iPhone
If you’re getting rid of your old iPhone, chances are it’s because you bought a new one. If that’s the case, you can and should transfer all your data from your older iPhone to the new one.
In order to do this, you need to turn on your new iPhone and use the Quick Start feature. Follow the instructions on your screen, and be sure you have your new iPhone connected to your Wi-Fi network and that you already set up Face ID or Touch ID.
It might take a while, but this is the easiest way to transfer all of your data and make sure you aren’t losing anything.
