Multiple iPhones using same Apple ID.
When I set up phones for my then younger children, I used the same Apple ID. Fast forward several years, and now they are older and I need to separate their Apple ID from mine as our texts are now showing up on their Macbooks, etc. I need to create a unique ID for each of them and combine them via Family Sharing.
My concern is losing the data already on their phones including pictures, contacts, etc. Will this type of information be erased when the Apple ID is changed?
Any help or suggestions on the least painful way to make this change without me being killed by my two children?
Thanks!
