Answer 1

What you need to figure out is to see if your code contains functions or structures that have been deprecated with PHP7.x.

As mentioned by Angel, reading the migration documentation and more specifically the backward incompatible changes and the deprecated features will help you check the compatibility of your code with your new environment.

You're not migrating from PHP5.6 to PHP7.0, but you're moving from one server with PHP5.6 to a server with PHP7.3, which will result to the exact same thing...
