Migration Plugin

It happens if I specify a name for a repo different from a pulp 2 one. E.g. I'd like to migrate rpm_unsigned.

 {
  "plugins": [
    {
      "type": "rpm",
      "repositories": [
        {
          "name": "random_name",
          "repository_versions": [
            {
              "pulp2_repository_id": "rpm_unsigned",
              "pulp2_distributor_repository_ids": [
                "rpm_unsigned"
              ]
            }
          ],
          "pulp2_importer_repository_id": "rpm_unsigned"
        }
      ]
    }
  ]
}
