Going from iPhone 4 to Xs Max
I am going to be upgrading from an iPhone 4 to an Xs Max. No I haven't been using it for ten years or however long its been. I was using a Galaxy S7 edge until the motherboard fried itself. My old iPhone 4 has been floating around in my home so I switched to it until this new upgrade cycle.
Anyway, on to the question at hand. (You probably already know what I want to ask.) I can't sync with iCloud, probably because my iOS is way behind. (iOS 7 point something) Is there a way to move my stuff from iPhone 4 to Xs Max?
iPhone 4, iOS 7.1.2
