do not change from DAPS to Jepps or vica versa, they are different in a few key areas of their layout that could be dangerous if your used to one format and not the other.
Since you said that your jepps are out of date by almost a year it will be easier to call Jepp australia and see if they can send out a ammendment package to suit, either a brand new set of plates or the years worth of updates.
