I did this and checked my devices on the login or account page (not sure exactly which one it was). It showed two devices, that were named “iPhone”. No idea, which one is the new one and which one is the old one. IT-support couldn’t tell either. So once I’ll have to hand in my old iPhone and delete it from the trusted devices / devices with authenticator, it will be a hit or miss game.

That’s the pinch. Sometimes it’s hard to tell which is which. I’m sure there’s a way, but it’s not something I would want to do.
My thought would be to delete everything and start over when you get a new phone.
