I am beginning to prepare for a vault switch from DB to SMTP messaging.

We would like to clean out the existing messages and notifications and start from scratch.  Going through the workflows and removing any state or transition notifications is simple enough, but was wondering if anyone has any knowledge or experience on a safe way to eliminate all existing messages and set up notifications in the database.

This would include:

1. workflow
   
2. user
   
3. project
   
4. document
   
5. etc...
   

Thanks,

Shawn
