Apple’s iOS 12.4 comes with a new iPhone Migration feature that is designed to make it easier to transfer your data from one iPhone to another.
This new feature allows you to transfer your data from one iPhone to another using WiFi, this can be done when the two iPhones are next to each other, once the handsets are paired the data transfer can begin.
As we can see from the video this is a pretty simple way to transfer your data from one iPhone to the other. It looks like Apple have designed it to be as hassle free as possible.
