iPhone 16 Pro iPhone 16 pro iPhone 12 switcheroo

[DeftwillP]

I'm working on fixing some things for my FIL who might be described as a technological luddite. His wife recently passed but not before acquiring a 16 pro and on an att installment plan along with an iPad Pro for him. He is currently using a 12 regular I believe but possibly pro. We're trying to help him sort out bills and accounting for personal matters but also for business as well so it's imperative that absolutely nothing is lost on the phones. I'll need to cut data on the at&t plan for her iPad and her phone so as to pare down their $300+ phone bill.

I wanted to just make backups of their phones to my MacBook Pro and I know that it wouldn't be a problem to take the iPhone 16 and set up with his iPhone 12 account. It should still have all of the same photos, passwords, etc.

Will we be able to take her iPhone 16 pro backup and install it on a 12? And more importantly, will all of the passwords be there? Can you export the passwords as a document file?

edit: am I overthinking this? Can we just do it all through the cloud? I'm just terrified of losing his passwords and info.

I'm not sure I 100% understand exactly what you're trying to do, but I do have a few thoughts:

Quick way to tell a regular 12 from a 12P - 12P has three camera lenses, the regular 12 just 2.

If you take a 16P backup and install it on a 12, you will overwrite everything on the 12. Is that really what you want to do?

May I ask why you're keeping the old 12, and not the newer 16P?

Passwords will definitely be a problem. Though an iCloud backup or an encrypted iTunes backup will save all the passwords, Many apps (especially financial apps) will recognize that something has changed, and insist upon the password being re-entered.

"Can you export the passwords as a document file?"
No.
