For all i know, there is no need to transfer the visa from the old passport to the new passport eventhough it is cancelled, just present, submit or bring the two passports with her. my wife renews her passport and her visa was attached to the old passport, they cancelled her old passport but the embassy (phil) told her to keep the old one because the visa is not yet expired. If your wife travels, she needs to bring/carry the two passports. Pls try to contact your embassy for other info
