Software Questions

Hello ,i am going to buy wyBuild software for my application. I am developing a windows form application (VB .NET) and i want to make clear some things if possible .So my questions are : 1. If i make changes to my project like a database schema update will the update to the end user delete the database data entered by the user so far as my application is using local database file included with my project ? 2. How the rollback of the update works ?

I am waiting for you feedback !

Updating the database is best described here..

2. How the rollback of the update works ?

If an update fails to install then wyUpdate rolls back your application state to the last previously good state.
