If they are dug up and moved while in the spring while they are leafed out, the shock will likely kill them.  At the very least, you would lose the flowers that appear in late summer/early fall.  They are best moved after the foliage finished storing energy in the bulb and turns yellow…general in late April.  More on them here:  http://www.bulbhunter.com/2010/09/23/red-spider-lily-buzz-lycoris-radiata/
