Can I keep using Elixir/Gulp after migrating to Laravel 5.4?

#No gulp file in laravel 5.4.

Thanks for the links; however I do not want to migrate to webpack as the project is already live and we just want to keep our build process.

So do I have to use Mix instead of Gulp if I want to migrate to 5.4?

yes, in package.json add elixir

npm install laravel-elixir --save

and remove mix from package.json

then remove webpack.mix.js and add your old gulpfile.js

Yes, you may freely use any tool that you want.
