Using Drush to manage migrations

With the migrate_tools module enabled, there are Drush tasks that allow you to run, view the status of, and roll back migrations. To view a list of migrations, you would run drush migrate-status, which will show a list of all registered migrations and their current status. Individual migrations or sets of migrations can be run using drush migrate-import, followed by a comma-separated list of migrations; an example is running drush migrate-import d7_user, d7_user_role. Once a set of migrations have been run, they can be rolled back by running drush migrate-rollback, followed by the list of migrations to roll back. Rolling back migrations will remove any entities or configurations they had created. For example, running drush migrate-rollback d7_user would remove any users created by the migration.
