Have you ever taken reclaimed hand-hewed beams and turned them into hardwood flooring?

I am looking for information regarding this. In particular, I am trying to determine if this was done, would:

1) it be necessary to kiln dry the planks before installing the flooring?

2) and would it be necessary to mill the sawed planks as tongue and groove to prevent cupping?

If you have any insight on this, I would be very interested in learning.
