In my observation, that rarely goes well. People tend to view it as a bait-and-switch.
What I have seen companies do with good results is to put the free product into maintenance mode, then develop a new (and improved) product (even if it could be considered a "version 2" of the free product) and put a price tag on it from day 1.
But this is speaking from my observations, not from experience. I've never tried taking one of my free products and converting them to paid, personally.
