You can do it. Don't listen to the naysayers. Loosen the spokes a little at a time so you keep even tension around the rim until everything is loose. Keep track of the position of the spokes in relation to both the rim and the hub so the spokes are installed in the same relatonship on the new hub. If the wheel is dished, you'll have 4 sets of spokes. Left-inside, left-outside, right-inside, right-outside. Just do one wheel at a time, so you can refer to the other wheel for referance.
