PvE to PvP Realm Transfers?

Because I do not play on any of the affected servers, the fact that Blizzard has opened up PvE to PvP realm transfers was not immediately obvious to me. Hyjal, Lightbringer, Shadowsong, Zul'jin, Alleria , Hellscream, and Whisperwind are all PvE servers, and have recently been given the opportunity to transfer to new PvP servers Black Dragonflight and Dalvengyr. This is interesting, primarily because Blizzard has, in the past, always kept realm transfers within their realm type. So these new transfers will allow seasoned players from old PvE servers a taste of the excitement of PvP without the difficulty that faces most players who wish to make such a switch - rerolling and releveling.
