What would be the proper steps to upgrade laravel version 5 to latest version 9

I have an old project which I developed in Laravel 5.3 and I want to upgrade the project to Laravel v9. What are the steps to upgrade?

What I have seen so far on the internet and from my knowledge:

Upgrade to each higher version step by step e.g 5.3 to 5.4 ... 6 to 7 to 8 to 9

I am running php 8 on my macos. And currently, my code is not running because of deprecated methods in php 5.6 that my Laravel 5.3 is using.

How to upgrade properly?

My composer.json file is
