I've searched Google and forums and can't find a clear answer on this; We're a family of 4 with me being the main iCloud family account holder. They've been members of our iCloud Family for years (for purchasing etc.) and i'm now interested in moving them all over to one single iCloud Storage plan. However right now 3 of them (myself included) all pay for our own iCloud Storage. If I invite them all to participate in the "family Storage" in my account, what happens 1. To their existing plan, does it automatically get canceled? 2. Their existing storage used; does it automatically get moved to my storage or do their devices have to transfer all of that again in my storage? There's no clear description as to what happens.
