Back in December, I unintentionally bricked my wife’s old iPad because I misunderstood some online instructions and thought I could associate it with a new Apple ID by doing a hard reset. Didn’t work.
Now I’ve just bought her a new iPhone SE (2020 model) and want to switch her over to it from her current iPhone 6s. She’s understandably nervous about this, since our lives now depend on our phones, and my experience with the iPad has made me a bit more concerned than I might otherwise have been.
I’ve been working with PCs for more than 40 years, and Android systems for at least 10, but I’ve never been an Apple person, and the iPad debacle has taught me that my PC- and Android-based assumptions and intuitions are not always valid in the Apple world.
So please help me transition her to the new phone as easily and painlessly as possible.
The Apple ID e-mail address in the 6s’ Settings (I’ll call it ID-A) is an older one and we can no longer access e-mail sent to it, so we want to change it to her current one (ID-B). We have the Apple ID passwords to both, so we can access both Apple and iCloud accounts online.
According to Apple, I can backup the old phone with iCloud or using iTunes on my PC, but I think there’s a problem with that:
Q1: If I set up the SE for ID-B, will I be able to restore the ID-A iTunes backup to it?
Q2: Do either of those backups include apps, account data, etc.? That page outlines what will and what won’t be backed up with each method, but doesn’t seem to say whether installed apps will be saved so that they could be restored to a new device.
Q3: What about her texts? How can I preserve her texting history?
It is apparently possible to change a device’s Apple ID, but that page isn’t clear about what happens to the existing data on the phone when you do that.
Q4: Is everything just left unchanged, or is it like switching to another user account, where you have a new desktop, data, and accounts, and the data and accounts of the old ID are no longer available?
If the former, it would seem that the best way to proceed would be to change the Apple ID of the 6s to ID-B, then backup everything and proceed with iPhone Migration. Somehow, I suspect that’s not what happens, and I’m reluctant to make any assumptions about it.
Q5: If the latter, is the old data erased, or can it be recovered somehow?
Q6: What other pitfalls should I be on the lookout for?
Thanks for your help.
