Answer 1

Migrations are meant to be applied and rolled back in a specific order. Therefore there is no "proper" way of reapplying an arbitrary migration.

In any case there are at least two options:

1. "Fail forward" - create a subsequent migration that creates a necessary FK and apply it. This is the only proper way if you are already in production.

2. If you're just in early stages of development and don't won't to bloat the migrations directory you can

   • dump the tables so that you preserve the data
   • rollback up to this particular migration
   • fix and test the migration
   • migrate
   • load the data from dumps

Answer 2

Unfortunately there isn't an option to rollback a migration per table basis. You can only rollback the latest migration or last few migrations using the step parameter.

But there is a hacky way to do it in case you really need to. You can set the batch value in the migrations table to a higher number than the most recent migration for only the migrations you want to rollback. With this when you call php artisan migrate:rollback, only that particular migration files with batch value altered would rollback.

I do it this way:

1. Deleting a table manually;
2. Going to "migrations" table and deleting corresponding row to your migration;
3. php artisan migrate;
4. done

For example, if you modified migration called "Settings", then you delete this table from DB and migrations table, then rerun artisan command.
