lol had the same question a while back too, and no you can't unless you move the save to the newer one vba-m.
oh and you should get the version w/ the link ability if you want it for pokemon.
check out my question on the answers page
the old vba adds junk to your save so unless you edit it you can't really transfer it, same goes w/ no$gba. no$ would add $!#$%!$ or something to areas of your save for idk what reason.
