I can't talk for Nikon, but for Canon it will depend on the lens. The EF-S lenses are crop sensors only and you do not need to multiply by the crop factor. EF lenses work on both but the focal length is multiplied by the crop factor.

I have 3 lenses, 2 of which will be fine if I were to upgrade to a Full Frame sensor.
