We have a large number of old Urls with FB likes that redirect (301) to new Urls. Is there a way to get FB to recognize the 301s and migrate or move the likes to the new Url?

A:
URLs that don't return a 200 aren't "likable" - this is intentional to prevent people from being duped into liking a URL they didn't intend to.
There may be some administrative channel for you to go through that will let you "port" your likes over, but honestly I don't think this is something they have a process for. At least not yet.
