I've also been (very slowly) working on automating the workflow for
migration to a level that it requires minimal user intervention. This
hasn't been tested or completed yet[1].
It is mostly complete, but if you can help complete it, it should
be a bit nicer than manually porting every list (i.e. multiple-commands per
list right now) vs single command with exception handling to keep
working till it reaches end. For 3k lists, it might be useful :)
