I don't think that we are very far from this because we can borrow some code from migrate_misplaced_transhuge_page(), and the experience in hugetlb migration will be also helpful. The difficulties are rather in integrating thp support in the existing migrate code which is already very complicated, so careful code-reading and testing is necessary. This topic was in my agenda for long, but no highlight at this point.
