If the state that you moved out of happens to be New York, the wages on the W-2 do not have to be corrected. Box 16 is equal to box 1, no matter how much you actually earned in the state. You show on your state tax return the amount of wages that you actually earned in the state. I don't know if there are other states where you could correct the wages on the tax return. Every state has different rules. So again, what states did you live in, what states did you work in, and what states were tax withheld for?
