    managementApplication,
    managementFeature,
    accessToken: managementToken,

  }
  if (proxy) {
    // contentful-import and contentful-export
    // expect a string for the proxy config
    // and create agents from it
    options.proxy = proxyObjectToString(proxy)
    options.rawProxy = rawProxy
  }
  return runMigration(options)
}
