Resolution
goal
Does the root domain have to be in native mode to migrate accounts with SID History to any of its child domains?
fix
No, the root domain does not have to be in native mode. When migrating accounts with SID History to a forest with multiple domains, only the target domain, in this case the child domain, would need to be in native mode.
