I'm changing iPads soon for school from a old ipad to a new ipad air. I was wondering if I used the same Apple ID, could have save the progress from the games or apps I have in the old ipad and keep them in the new one. I know it saves the game so that you don't have to pay for it again just in care it isn't free. But, let's say I wanna save my Flappy Bird high score. If I get the app on my new ipad air, is there a way I could open the app up without having to start from 0 again. Also, documents in the notability app, is their an easier way to transport them to the new ipad. And music as well? Thank you very much!
Yes. You can transfer all data from your old iPad to your new one with a backup, either with iCloud or iTunes on your computer. There is probably not enough space to backup to iCloud, but if you back up to a computer with iTunes, and then plug your iPad Air into that computer, it will ask if you want to set it up from the backup of your old iPad.
