'Forward Engineer' flush all my tables... (1 reply)

I created tables and insert some test data inside.
After that, i 'reverse engineer' to create relationship and FK for the tables.

Once done, i 'forward engineer', here is my problem (i m using WB 6.1 community) under "Set Options for Database to be Created",
- if i UNCHECK all option (default) and click 'Continue', the FK, relationships will not update my schema.
- if i CHECKED 'Drop objects before each create object', then it update the FK for my schema but it FLUSH all my data.

Is there a way to update FK, relationship and at the same time remain existing data?

Thanks for the pointers.
