During the system-managed Cleanup phase, the system will notify all connectors of the Structure State Change event, deallocate the old instance of the structure, and resume access to the structure so that the queued requests can be driven against the new structure. Connectors do not need to respond to the Structure State Change event.

At the conclusion of the Cleanup phase, the system delivers the Structure Available event to all connectors and may also deliver the Alter Begin and Alter End events as well.
