Changing iphone

Hello sadeq50! I hope you are doing well.

In order to upgrade your iPhone, do the following:

Go to the Apple Store or order online a brand new iPhone 15 Pro Max. Unfortunately, Apple will not allow you to trade in your iPhone 15 for your new iPhone 15 Pro Max, so you will need to keep your original iPhone.

For more information, please click on the following link:

Transferring to a New iPhone:

Use Quick Start. If you a transferring to a new iPhone, then this is the link to use: Use Quick Start to Transfer Data to a New iPhone, iPad, or iPod touch - Apple Support. Use Quick Start to transfer data. If you have iOS16, then the iOS cannot be downgraded (and as a result, things would no be just like your iPhone 7).
