yes, it's a good idea to make a reservation at your home resort at 11 months (certain times of year it is essential.) then at 7 months, if there is availability at another resort that you prefer, you can cancel your original reservation and book the new resort for your original dates.
(in rare cases, the new room is booked up by someone else between canceling the old reservation and trying to book the new resort...so it's ideal if you have enough pts to make the new reservation first, before canceling...but it's not a common situation from what i understand.)
if there's no availability, you can still request to waitlist for a reservation at the new resort.
just don't think in terms of a "transfer," though. you do have to cancel and rebook.
