Extending Cases in Database

Hi all, I need to extend cases table into two new tables which will inherit some of the characteristics of cases table. Can anyone help me on how can i do that, and will the change cause catastrophe in the database?

In Module builder, you can create a new module and base it on the “Issues” template. This will bring in similar fields to the Cases module.

But note that doing this won’t really bring a second Cases module into your system - all the custom code (and there is a LOT of it for this module) won’t be there.

My advice would be to use a single module, but separate the use of it. So add all necessary custom fileds, and use Security Groups to limit who sees what. If necessary add custom code to generate two different views for each kind of case.
