>I imagine a prg could be written that could step through the .frx and make whatever adjustments would be necessary and add the records to a dos .frx. Wouldn't be perfect but could be a good starting point. Not sure if it is feasible or not, I guess Cathy would know. Do you know if there is any reference around that annotates the difference in the tables for the versions?

Did you look at the references that come with VFP? Look in the Tools\FileSpec directory.
