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. Plus you will also loose some of it to ferile bees and wasps.
If you extract it now and put those empty frames back on with your supers you will have this years honey in your supers, and then after you have extracted the new honey this year, you can feed last year's honey back to the bees as needed
