Migrations in Laravel is like having version control of your database. It gives you the ability to create, modify and share a schema, as well as drop tables. Since it has version control, you can migrate and rollback your database changes with just a couple of CLI commands. Here’s a couple of examples.

To migrate:

$ php artisan migrate

To rollback:

$ php artisan migrate:rollback

In addition, you can also create a new migration table.

$ php artisan make:migration create_users_table --create="users"

It will create a file similar to this:

app/database/migrations/2015_01_01_213247_create_articles_table.php

which you can modify and add fields.
