That's an odd one.

2: Elder’s Grace (Ex) You immediately age to the next age category, gaining all of the appropriate bonuses to your mental ability scores without taking any penalties to your physical ability scores. If you are venerable when you achieve this boon, you die and become a ghost. Any illusion effect you create gains a +2 profane bonus to the save DC. This transformation into a ghost persists even if you fail to perform your obedience.
The last sentence - "This transformation into a ghost persists even if you fail to perform your obedience" - would seem to indicate that the aging does not normally persist if you fail to perform your obedience but the ghost transformation does.
