Seeking Guidance for Migrating Laravel 5.4 Web App to a New Domain [closed]

I'm in need of your valuable advice.

We are currently working on a Laravel project, and our Laravel web app is connected to a mobile app via an API. Now, we're planning to move the web app to a new domain. However, there's a catch - our Laravel version is a very outdated 5.4 version, and unfortunately, we've lost access to the source code. Luckily, we do have a server backup file.

Could anyone kindly suggest a method for deploying this code on the new domain?

Thank you in advance.
