When you get the new device and go through the first time startup stuff, one of the questions is if you want to set it up as a new iDevice, transfer data from your old one, or restore from backup (iTunes or iCloud). If you choose transfer, it will create a wireless bridge between the 2 devices and transfer almost everything. Biometrics and CCs definitely do not transfer, and I think that apps will have to re-download (it's been a couple of years since I've last done this).
