As already posted, when you are booking inside the 11-month window, you need to pay with home resort points. If you want to book AKV 11 months out, you need enough AKV points to pay for that reservation. Transferring points from somewhere else into your membership doesn't cause them to change their identity. If you have 100 AKV points and transfer in 25 VWL points, you have 100 AKV points to use at AKV 11 months out and you have 25 VWL points to use at VWL 11 months out or at AKV at 7 months out.
Another thing you should know is that even though you purchased a contract at a different resort, because it's the same UY and provided you titled it the same way,
DVC should set up that new contract as an "add on" to your membership. The good thing about having your contracts under the same membership is that you don't have to transfer points from one contract to another. You can simply combine points from the two contracts when making a reservation in the 7-month window. And you can do this online when making the reservation.
Transfers are done when someone wants to move points from one membership to another membership. If you receive a transfer of points from another membership, those points will not be visible online unless they are the same resort and UY as a contract in your membership. Otherwise the transferred points are tracked some other way and only MS can see them and use them for a reservation. Therefore, when you want to use those transferred points to make a reservation, you have to call MS. MS opens at 9am, online booking rolls over to the next day at 8am. That one hour delay can make a difference when you are trying to book a hard to get reservation 11/7 months out.
