This option is available from the Bunker RVG right-click menu and is enabled only if the Primary host becomes unavailable. When a disaster occurs at the Primary host, before performing a takeover on the Secondary, you may want to make sure that all the updates on the original Primary are available on the Secondary. You can do this by activating the Bunker RVG, converting the Bunker Secondary to a Bunker Primary and then replaying all the pending updates that did not reach the Secondary. After the replay completes, you can choose to deactivate the Bunker and convert it back to a Bunker Secondary and perform takeover on the up-to-date Secondary or restore the original Primary if it becomes available again.

After the replay of pending updates from the Bunker Primary to the Secondary completes and the Secondary RLINK status is up-to-date, it is ready for takeover.
