A computer-implemented data processing system, comprising: a data update component of a destination for receiving a copy of an original changelist of data changes from a submitter and updating the changes to destination data of the destination to create updated destination data; a ticket component of the destination for generating a destination ticket related to the copy, and sending the destination ticket to the submitter; a data component of the submitter for managing the original changelist based on a status of the data update at the destination, the submitter to lock the original changelist based on receipt of the destination ticket, the data component to merge the locked original changelist with a new changelist when the status of the data update at the destination is failed and the new changelist exists, wherein the data component unlocks the locked original changelist and the original changelist accumulates new changes, when the status of the data update at the destination is failed and the new changelist does not exist; and a processor implementing one or both of the data update component or the ticket component.
