Traditional NI-DAQ (Legacy) vs NI-DAQmx

NI provides the Traditional NI-DAQ (Legacy) driver to support developers with legacy code needing to run on 32-bit versions of Windows Vista, Windows 7, and Windows 8.​  NI-DAQmx replaced Traditional NI-DAQ (Legacy) in 2003. NI strongly recommends using NI-DAQmx for new designs and migrating existing Traditional NI-DAQ (Legacy) applications to NI-DAQmx. Please review the Getting Started with NI-DAQmx guide for more information on migration.
