Can it be done? and how?

zone 5a/5b Ontario Canada. Currently have under a magnolia tree 21
started shoots of Lily of the valley. Spaced about 6 inches/15 cm apart.

I have in another part of my property lily of the valley that is really
starting to self grow to the point where I have to cut it back. It
really took off in that part this spring. So I would like to transplant
another 20 shoots to under that magnolia tree.

Can it be done?
