The current production machine named app01 will be taken off the network and shutdown. The new machine currently named app02 with an instance of app02 on it will be renamed to app01. Once renamed to app01 and we do sp_dropserver app02 and sp_addserver app01. We simply see the field datasource populated with the server name in sys.servers. We just wonder if that also flipped\updated after sp_addserver app01. We don't see a reference to that field in the sp_addserver proc.
