We've noticed through the CWMS client applications that if an LRTS exists, using the old LRTS identifier still allows for time series storage and retrieval. The confluence document stats 6 = new LRTS IDs are required on input and are presented on output. The problem with the old time series succeeding is that the retrieval doesn't fail, but the returned time series id along with the data is in the new format, which causes conflicts when attempting to match the requested time series id with the returned time series id (especially in multi-retrieve).
