A:AnswerVery simple, just follow the instruction on the new iPad when you first turn it on. Make sure you backup the old iPad to iCloud. When you log into your account with Apple, the new iPad will download everything to your new iPad.
A:AnswerSure, you need a lightning breakout adapter of some kind. I would recommend a Lightning Hub, they allow for many more types of connections than just HDMI. The apple branded adapter is not worth it.
