I´m using DatabaseMigrator to deploy DB changes to a lot customers databases in the same server.
The problem is:
All commands are processed every time that I run the program, but I realized that it rans the same command already proccessed before like:

• 12/03/2010 09:56:02 -> The relationship 'FK_tb_ped_compra_tb_item_pec' was created successfully.
• 12/03/2010 09:56:09 -> The relationship 'FK_tb_tit_pag_tb_tit_pag_ccusto' was created successfully.
• 12/03/2010 09:56:09 -> The relationship 'FK_tb_tit_pag_tb_tit_pag_proj' was created successfully.
• 12/03/2010 09:52:50 -> The table 'tb_tit_rec' was successfully altered.

Other thing:

• 12/03/2010 09:52:42 -> The relationship 'FK_tb_tit_rec_tb_tit_rec_ccusto' was successfully dropped.

If DatabaseMigrator drop my FKs, what is happen if I run it over a DB with real data?

Tks guys
