Going to small cell

[Rabbitdog]

I would like to switch over to small cell and have a few questions about the process of conversion.  First, is it necessary to switch out all of the comb at one time or can I just insert a frame or 2 when convenient as other old comb comes up for replacement.
Second, is it a tremendous stress on the bees to go straight to smallest size foundation or should I first raise a generation on 5.1?
thanks!
