Compared with iTunes, TunesGo is better in transferring. It imports all iTunes Media like videos, music, TV Shows, etc. to your new iPhone 7 / 7 Plus quickly and easily. Without erasing any existing data on your iPhone 7 / 7 Plus.

iPhone 6S / 6S Plus, iPhone 6 / 6 Plus;
iPhone 5S / 5C / 5, iPhone SE, etc.
