Actually, not that much from Susning could be migrated due to license, rights issues. The creator of Susning, Lars Aronsson is very active on Swedish Wikipedia. As far as I understood him, the content he knew the rights to (his own) could be migrated. But since the wiki is a collaborated effort and Susning had such licensing terms most stuff could not be attributed and is stuck in Susning.
