This option is useful if you want to perform custom actions after the unload/reload and before the qaagent upgrade. Use the
-sur option if you are upgrading from a pre-10.0.0 message store and you want the Agent to automatically perform the unload/reload
step for you.
If you are upgrading from a pre-10.0.0 message store, you must first manually unload and reload the message store.
This operation exits when the upgrade is complete.
