       - All upgrade readiness checks passed successfully and there is nothing
         to do.
     * - 1
       - At least one check encountered an issue and requires further
         investigation. This is considered a warning but the upgrade may be OK.

       - There was an upgrade status check failure that needs to be
         investigated. This should be considered something that stops an
         upgrade.
