Playing hockey in rollerblades

lol
Umm On sat I played forward in roller blades for the first time, just learning how to rollerblade, Ive been playing roller hockey for about 2 years but never actually in rollerblades lol.
Does anyone have an Idea of how long it takes to adapt to the rollerblades from ice skates while playing net?
I want to try next season on rollerblades but I dont want to screw up my game and really suck because of being on rollerblades. Any suggestions on learing to goalie rollerblade?
Thx
Chris
