Ryan, The LDM is designed with backward-compatibility as a requirement. If you look at the rtstats(1) webpage <https://www.unidata.ucar.edu/cgi-bin/rtstats/siteindex>, you'll see that old and new versions of the LDM work interoperably. Newer versions of the LDM are likely to use fewer system resources, however, because they disallow certain inefficient configurations (like making overlapping data requests). If you ever do encounter an interoperability problem, please notify address@hidden immediately. > Are there any known issues (or inefficiencies) with older versions of LDM > (in this case 6.7.1) talking to new versions (6.11.6)?
