However when non-NMDA clients communicate with NMDA aware server, it is not clear whether the NMDA aware server can use existing operation to return the same results with \textless{}rpc-reply\textgreater{} as non-NMDA-aware server does. This document identifies some of the major challenges, and provides solutions that are able to mitigate those challenges and smooth the migration towards NMDA deployment.}, }
