I am trying to put laravel migrations in database sub folder, but not sure how to do this.
When creating new migrations and executing your migrations, you can pass in a path
parameter through the command line interface to specify the directory it will use to create and run the migrations respectively.
php artisan make:migration create_users_table --path=/path/to/your/migration/directory
php artisan migrate --path=/path/to/your/migration/directory
