How to back up two iPhones to one computer
I have backed up my 2 iphones 2 files (X and 13) in icloud. Now I want to transfer both backup files to the iphone 13. I am wondering how do I sync such that no data is lost from both phones?. I keep reading there is no way to merge 2 backup files unless I use third party app. So my question is if I sync how do I sync such that no phone overwrites the other. Thanks so much
iPhone X, iOS 16
