Could you please explain further why the MDT might not have the FLD entries? Is that an interop issue, due to corruption, something else? |

Yes, it is an interop issue. So during rolling upgrade, when new OSTs communicate with old MDTs, which do not have FLD entries, so the new OSTs should stop keep trying in this case. |
