Yes, just whack it back to about a foot, bring it inside and move to a sunny window. A few leaves may yellow and drop, but don't worry, it will soon adjust and start growing again. Put it back out in the Spring. I've overwintered the same vine for 5 years or more. The only problem that I have with it indoors is mealy bugs, which can prove to be persistant.

I kept a pink one in my sunroom on a trellis a few years ago. It did survive until the next summer, but be aware they are very prone to mealy bugs and spider mites when indoors. They probably have them when you bring them inside. In spite of the best sprays and monitoring, you may be fighting bugs. That said, I'm a glutton for punishment. This year I brought inside a beautiful red mandevilla vine. I'm growing it in a hanging basket. I figure I'll keep it short until next summer, then put it on a trellis.

I agree with vtandrea, mine was infested with spider mites. I couldn't get rid of them. I just wound up throwing mine in the garbage and bought a new one this summer.
