Kirito's SAO avatar is not something that he can just port like he can with his ALO avatar, since SAO is no longer present. However, since ALO is a copy of SAO, it has a copy of all SAO player data, and thus allows former SAO players to "import" the data in the creation of their ALO avatars. Only an imported character can be converted to other games. Kirito cannot convert his SAO avatar because he chose not to import the avatar to ALO, since he wanted a fresh start. He has a thing against his SAO persona.
