[Jonathan Olivas]

I'm curious on if it's possible to transfer wrestlers and arenas between wwe smackdown vs raw 2006- smackdown vs raw 2011 video  games?? I have all the games for psp ps2 and even ps3 I've heard about this being done before even  seen a couple but I'm pretty new at this lol so Please help. If you know how to  do this or atleast know a couple things on the topic please message me or comment down below thanks in advance.
