foliage requires roots to keep it supplied with water. unless you can lift up a cubic metre or more of soil with all the roots in, loss of roots is inevitable, which will cause the foliage to wilt and die.
accepted wisdom is cut back the above ground parts to match the smaller root mass, it will grow back when it's ready.
Whenever I’ve taken a cutting the advice is always remove the leaves as they require energy to grow. But you wants the roots to be getting established. Not sure if the theory is the same.
My thinking is if the roots can use all their energy to get established the foliage will come later.
