I would not trim them back. This time of year, they will soon be going dormant, and all above-ground growth will die of naturally once we experience some overnight frosts/freezes. The carbohydrates and other stored resources in the top growth (plus additional carbohydrates from whatever level of photosynthesis it's still capable of carrying out) will be sent down to roots as dormancy approaches, and it would be valuable to the plant to not lose those energy stores.

Just keep the new plants carefully monitored for watering until the ground freezes so the roots, which will be stressed by the move, do not get too dry. Even if the current set of leaves scorches (desiccates and browns on the edges or tips, or if entire leaves are "sunburnt"), since they weren't accustomed to a light exposure as intense as several hours of direct sun, it's not a major health concern for the plant and they can be ignored for now.
