I had a customer with an insight and moved him to the FMD (same data format as the Fmx) and we had to take a few stabs at it but SMS did convert it all fine.  He had several lines in each field and those made it over also.

I do not have SMS but the customer and/or his CNH dealer had the right version to get it done.  There are serveral export options some which did not get the whole client/farm/field/multiple ab line arangement over but eventually we found the right one.....can't remember which one it was.....but it did convert over.
