I actually made the exact same transition....Cirrus, Baron, Bravo....don't sweat it one bit. If you have been flying professionally your IFR skills shouldn't be an issue, don't expect something you've never seen or heard of. Initials are basically learning the systems and locating where everything is in the cockpit. The instructors are there to pass you, remember this isn't the FAA. I remember my first type ride the instructor telling me that by the end of the day I would have my type...if I screwed something up on the first try we would finish the rest of the ride, retrain on the deficiencies, and finish up with a retest on that particular item. I really wasn't nervous but that did seem to help. Fortunately I didn't have any problems....
Orlando was always a nice place to train, which is where I did and still do all of my Bravo training. I'm not a Wichita fan, the city...never been to a school there.
