Roll back a specific migration without rolling back other migrations

I mistakenly ran the second to last db migration wrong, but the last migration is fine. Now I want to roll back my second to last migration without reverting the last migration. Please share your knowledge with me and others.

You can specify your Migration file version number to rollback that Migration.

You can achieve it by either of these

rake db:migrate:down VERSION=your_file_version

OR

rake db:rollback:up VERSION=your_file_version
