Presumably, with some lists on 2.1, and others on 3.0.

That would mean the admin would need to be able to specify which lists to migrate. 

I guess you might want to consider whether special handling is needed for virtual domains. I know we’ve been operating a nasty cludge, where we’re using SUBDOMAIN_LISTNAME at DOMAIN for an internal representation of LISTNAME at SUBDOMAIN.DOMAIN. I suppose that’s unusual or unique, but it might be nice to allow migration of a list in 2.1 to a list with a new name in 3.0.
