Laravel Migration table already exists, but I want to add new not the older

In v5.x, you might still face the problem. So, try to delete related table manually first using

php artisan tinker

Then

Schema::drop('books')

(and exit with q)

Now, you can successfully php artisan migrate:rollback and php artisan migrate.

If this happens repeatedly you should check that the down() method in your migration is showing the right table name. (Can be a gotcha if you’ve changed your table names.)
