/**

 * Get a user migration status

 * Fetches a single user migration. The response includes the `state` of the migration, which can be one of the following values:

*   `pending` - the migration hasn't started yet.

*   `exporting` - the migration is in progress.

*   `exported` - the migration finished successfully.

*   `failed` - the migration failed.

Once the migration has been `exported` you can [download the migration archive](https://docs.github.com/rest/migrations/users#download-a-user-migration-archive).
