Yes i agree may be a very complicated thing to do for some,and far too heavy for most,perhaps i,m just used to always moving hives,lifting ect.
No need to run up and down stairs with them first though,just lift and rotate.
Take note of health and safety,and don't get involved in beekeeping,very dangerous buisness.Lifted/ hefted lots of hives yesterday,including floor and crown board,i think you would find this more or less impossible.Perhaps in a few years i may not be able to,but at the present moment i find no problem at all in lifting full brood box's,and carrying them,i use them as supers as well.
If you are a senior citizen,or a lady,or disabled,or younger but just a wimp,then you should change over each individual comb into another brood box, which you will of course have sat on the floor,same procedure when you put on clean floors in spring,if you do,and you are unable to lift the brood box. Or you could get some help with the lifting perhaps.
