Question

I have a table pictured below that has a surrogate Key as the Primary Key, and also two columns that represent a parent child relationship. Currently, the Primary key is OfficerPeopleID. The Parent is MgrPeopleID, and the child is PeopleID.
I want to use the current Primary Key (OfficerPeopleID) as the new child, and create a new field that will be the new parent. By doing this, the child will now be a primary key, which is my goal. How do i populate the new parent field to create the same hierarchy structure as the current parent and child fields are doing?
Thank you!

Do it in your ETL…

UPDATE  a
SET     ParentOfficerPeopleID = (   SELECT  OfficerPeopleID 
                                    FROM    OfficerPeopleDim 
                                    WHERE   PeopleID = a.ManagerPeopleID)
FROM    OfficerPeopleDim AS a
