Aidan,
NetCDF4 and netCDF4 Classic, actually *all* of the format variations, are
intended to present a uniform and seamless interface to the user, unless
advanced features are used. I am curious about your reasons for wanting to
convert. I wonder whether you have run into the same issues I have hit,
application software that changes behavior in a format sensitive way when
reading.
Sorry to distract from your real question.
