I do it every year. I pot them up, with new soil. Then trim them back quite a bit. I put them under a flourescent light that is on a timer, but you could put it in a bright window. Dont overwater, and watch for bugs. It may get a little ragged looking, but when you put it back out side it will rebound well in the warm sun.
Actually, you may want to treat it with some insecticidal soap spray before you bring it in. YOu dont want to bring critters in to infest any other plants that you have.
