Branflakes (community manager) goes onto say that the changeover is instantaneous too.

One poster mentioned that you could buy the LTS now, and wait to apply the code under after you get the remaining time and stipend from your existing sub. - No idea if that is accurate info though. Maybe you have enough time to submit a ticket to ask for an official reply, or better yet, you might have more luck tweeting pwebranflakes on twitter about it.
