Does your old phone have iOS 11 or later and Bluetooth turned on? See the following from Use Quick Start to transfer data to a new iPhone or iPad - Apple Support
If your other iPhone or iPad doesn't show options for setting up this iPhone, make sure it's running iOS 11 or later, and has Bluetooth turned on. You can also set up this iPhone manually.
