qauagent -su -c "connection-string" ...

This option is useful if you want to perform custom actions after the unload/reload and before the qauagent 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.

This operation exits when the upgrade is complete.

This operation cannot be undone.

To upgrade from a version 9 database, first, unload and reload the database:

dbunload  -q  -c "UID=dba;PWD=sql;DBF=qanywhere.db" -ar

Next, run qauagent with the -su option:

qauagent -q -su -c "UID=dba;PWD=sql;DBF=qanywhere.db"
