transfer from one apple to another apple phone

There are several ways. Quick Start was mentioned. I rather like doing it via a backup on a computer, especially since it's a very good idea to have a backup anyways. Also from iCloud, although that might require a large storage limit and there's less control over when it backs up.

Use the Finder or iTunes to transfer data from your previous iOS device to your new iPhone, iPad, or iPod touch - Apple Support

Apple also has a method of transferring data to a new iPhone when it's purchased online from Apple with the same Apple ID used in a phone, where the data is proactively backed up for later transfer to the iPhone. Did you purchase it directly from Apple online?

Very easy, bring old iPhone (unlocked and open to the home screen) next to new iPhone. Learn about Quick Start here: https://support.apple.com/en-gb/HT210216.
