If you put the frames out for the bees to empty/rob out, they are just going to put it right back into the hive, Causing the bees unnecessary work, and you haven't accomplished what you wanted.
If the frames are moved away from the hive to be robbed. The frames will be cleaned and any honey put back in the hive will be where the bees want it and will be new honey ..... right
If you have a flow going don't be surprised if they don't move it as quick as you prefer as in the time limit you need the empty frames.
As said above. If you scratch the capping, placed above the inner cover, bees from outside can not get to it to promote robbing. The bees once again place it where they please. The best way for that single hive to benefit. For me, here in the South, that may cause an SHB problem. No SHB for you right.
Honey does not spoil as you know. Just place the frames back on the hive. The bees will fill the surrounding comb and spaces. A few combs of last years honey with this years would be no biggie to me
Someone else tell me, do you really see the old honey as a problem?
