Since transferred points retain their use year and resort, if those points are banked, i think they will become Feb 2013-2014 points which will have to be used by Jan 31, 2014. I have not done a transfer so no personal experience.
That is assuming transferred points can be banked (I think they can). They cannot be borrowed I believe. I often get that mixed up, one is allowed, one is not.
PS- it probably would have been best to start a new thread vs. posting on this 8 year old thread that someone bumped for some reason today - zombie thread! This is also a Member Services type question but I know the thread was already here in the Purchaing forum.
