Jorge,

I see 3 solutions:

1. Do it by hand. Extract all the code from your .DBC by using GenDbc or GenDbcX from your first and second version. Check the differences between the two files and build a procedure that will set everything straight. Seriously, this does not seem a viable option.

2. Use Stonefield DataBase toolkit.

3. Use xCase. This product has all your new .DBC information in its model. So by distributing the xCase files and an update.app that comes with it, your customers will be able to update their .DBC. www.xcase.com . I made a review of xCase a while ago and it's available on my Web.
