To me this is a bug and serious design flow. I have mentioned few times in the forum and to QT that if person places an order on the site this person is a customer. No matter if they have registered or not.
Started with when email as login was implemented anon customers do not get an entry in customers table hence they are phantoms. The only entry for them is orders table. But trying to only replace userid may not work as there is more info which they may have provided differently as anon customers.
Not saying that having anon customers in customers table would solve merge problem but would make it easier to do this probably.
