If your development database already has the change that is captured in the migration script you can mark that migration as applied. For example, you've hand-written a migration script to cover a change that is already on your development database without using the generate migrations workflow.

When you mark as applied, the migration log table will be updated to prevent running the migration against the database without the migration script being run.
