Upgrade from Laravel 4.1 to directly Laravel 5.3

I have an app which was developed 3-4 years back in Laravel 4.1 and as per the current need I've been asked to port the web application written in Laravel 4.1 to current stable and recent version of Laravel 5.3 directly (without stepwise upgrade to 4.2/5.0/5.1 or 5.2). Is it better to port which may take a lot of time due to architectural change difference or rewrite everything from scratch in the latest Laravel 5.3 version?

Thank you,

Rohit
