Instead of terra-forming another planet, how about using that planet's conditions to gain experience with adapting to another world? When humans went out of Africa, they adapted, like getting more serious clothing and learning how to cope with new environments. It's time now to do it again, like learning to step outside our cradle - accepting a new way of life, as creatures dependent of life-keeping tech. That's the way of limitless expansion in universe, not trying to stretch each new place to fit our fantasy. (Well, we may do a little bit of both, but spinning planets out of their orbit is a bit extreme.)
