Hi
Glad that you're up and running.
I haven't tried changing on the fly. I think it's fairly unlikely that it would just work, because you need to create all the database tables (at a miniumum), so you would need to re-run at least part of the config tool. You'd also need to install the correct jdbc drivers, modify the DataSource file, etc, etc.
My suggestion would be to bite the bullet and re-install - I think you might find it easier in the long run.
