So I realize why I have duplicate customer data. But I want a routine to clean up my anons and assign the orders and related addresses to what I deem the master customer record(based on a strict matchcode) which is registered. If I reassign orders and addresses to my registered customer ID, are there any other records I am orphaning that I should reassign?

Secondly if I do this and run monthly maintenance, will it clean my orphans up? I guess in the second part I am asking if anyone has a records of what the monthly maintenance actually transacts so I can understand it?
