No, these are real estate contracts. You would have to sell the one and purchase another.
While you can sell back directly to Disney, the amount they offer is considerably less than what you would pay if you sold on the resale market.
Then you could only purchase the other resort if there were actually points available. And if you owned somewhere else also, then you would have an existing use year month so the new purchase would have to match that also.
Even if Disney decided to allow an 'even' exchange, there would still be legal costs involved including closing costs etc. So it couldn't just be a simple swap of points. They would have to charge some type of fee to cover all the associated costs.
