Diann - if you have to move your tree peony, dig a wide berth around the plant and go deep. The tap root is very deep - I went sideways too early in digging my red one out and broke off the main root. It never recovered. I thought it would have have lateral tubers like the herbaceous ones.
My kinkaku is way in the back of my bed and is hidden, but I have been too leery to move it. Let us know if you are successful. It may inspire me to try again.
