If you're going to move them, you should do it now while the weather is still a little 'coolish'. There will be transplant shock but your bulbs are so large they should contain plenty enough stored energy to see them thru the move. For those plants that are still in the ground, try to move them as a clump. Try to keep all the roots intack but if you cut or break a few, don't worry, the bulb will grow new ones. Plant all the large bulbs at the same depth they were before. You can tell that by the color of the old stem. If you discover new little baby bulbs along the way, plant those in a new seperate group about twice their diameter deep. Because of the adjustment required by the move, your plants may flower a week or two later this year. Also, flowering is hard on a plant so if some plants look distressed when they bud out, it's best to cut the flowerhead off just above the leaves. That way the energy normally used for flowering will be stored back into the bulb for next years growth and many more flowers.
