- Analyze different between your current BDM database, and the new definition
- Provide you the delta
- provide a SQL Script to execute to update your BDM

So, you can check the SQL Script, add your own feature (give a default value to a field who becomes mandatory for example).

You want more information? See a real-life video!&nbsp;[https://youtu.be/6kq5WRu5kGk](https://youtu.be/6kq5WRu5kGk)

At final, when SnowMobile does not detect any delta, update your BDM in the Bonita Portal.
