I have an application installed at diferent cient sites, now I have made an updated version of the application, this new version uses new fields in almost all tables used, all the tables are in a single one DBC, the question is how can I update the DBC at the client site within the version application the fist time is run.

The new DBC could have new field captions, new fields, new or different valiation rules, etc...

I know that I can't just replace new DBF files, either replace only the .DBC .DCX and .DCT files because the Tables and the DBC will loose their sincronicity.

Any one has an approach that wants to share?
