I have a 50GB plan that is almost used up. My wife has a Apple One plan 200GB that she shared with our family (including me), but my phone only syncs to my 50GB plan.
If I cancel my 50GB plan, data would still be available for 30 days. Would the data automatically transfer to a new plan, e.g. my wife’s Apple One plan? Or what happens when she cancels her Apple One plan and I start a new one? Would her data transfer over to the one I would buy and share?
Documentation on this is not clear, and I don’t want to lose my data.
As soon as your 50GB plan cancels your iCloud will go to “read-only” and won’t sync until you have enough storage.
After canceling you can go to settings, family sharing, and then enable your spouse’s iCloud+ plan and your iCloud should start syncing again.
I would recommend making a backup of everything on an external drive of course. There is never any guarantee that apple won’t lose data but I did this process a month ago and it was completely seamless.
Hearing that you made this step successfully gives me hope. But yeah, I’ll run the iCloud downloader first to have local backups.
