I'd suggest nipping down to you local on a quiet moment, Sunday afternoon or a weekday, and asking the staff to show you how the new structure works. They are (usually) well versed in explaining in a thorough and non patronising way to give a good grounding. They could show you which of your existing gear is still useable, and what you may want to consider getting.
Just remember the pinch of salt to sprinkle on their sales pitch.
