Working Extracts

The upgrade process will need to ensure that all data is up to date at the HUB where pre-scan data checks will need to be made. Working Extracts cannot be propagated as they are specific to a single location. As a result all data MUST be flushed, and claims released from the Working Extract into its parent. This is only true for working extracts; all other extracts do not need to be flushed, or have their claims released, as they will be available at the HUB.
