What can I do with this comfrey now?

I bought a bunch of comfrey roots (bocking 14) last spring and planted them in a raised bed where I could keep an eye on them while they started off. Unfortunately I had no idea how big they would get and they are way overcrowded. Can I move them now (zone 6b eastern Massachusetts)? Or wait until spring?

Also I read not to chop leaves their first year, but the plants are so close together I thought it might not hurt them too much?

Any advice welcome!
