Redmine

I would like to have have a project have individual issues, users, incoming email address, outgoing email address, and admins. Best way I can think of doing this is setting up another database and having them operate from there, which I've already created. I'm just trying to bridge the gap of setting my current Redmine installation of using that database for the other project. I've already added entries in the configuration.yml and database.yml, migration worked fine just don't know how to point to it.
