Did the DAFNE course a good few years ago but didn't have to do the another course prior to changing to a pump, I just had some one-to-one sessions with my DSN discussing basal rates and pump settings and then a session with the pump rep on the change over day.
I'm sure you too could discuss the basics with your DSN without having to do another course, if you purchase the book Pumping Insulin it just about covers everything you need to know and is a handy book to look back on when unsure of anything.
