The answer to this question depends on the country that issued the visa. There are two general situations:
The visa in your old passport is accepted in conjunction with a current passport. You need to bring both passports but no other action is required.
Example: Will my Chinese visa still be valid if I renew my passport?
The country that issued the visa requires that the visa be in a current passport. In this case they will offer a service that transfers your old visa to the new passport (they will print a new sticker and affix it to the new passport, and do something like punch a hole through the old one to invalidate it).
Example: (New Zealand) Transferring my visa to a new passport
