Qurbaani & Halaal Slaughter

Qadha of missed Qurbaani

Q: A person did not make a waajib Qurbani one year thinking that he did not own the amount of nisaab. He instead made a nafl qurbaani. After some years he realised that he had wealth put away which would have made qurbaani waajib on him. What does he do? Will the nafl qurbaani be counted for that years waajib qurbaani?
