I've never moved it at this time of year. I would only do it when it's dormant in the winter. But if I had to move it now I'd take off all the stalks/leaves, dig a very big planting hole and incorporate lots of organic matter and keep it really well watered. And if it produced new stalks this year, I'd leave them on the plant. My test question for this kind of situation is 'will I be broken-hearted if it doesn't work'.
