You may need to restore your databases due to a failed upgrade.
- If you think the upgrade failure or its cause may have damaged your databases,
restore the databases from backups. For information about restoring databases,
see the System Administration Guide.
- If you are concerned about the possible corruption of your
databases, exit Server Config, but do not attempt
to restart the upgrade session until you have restored the databases
from backup. After restoration is complete, retry the upgrade.
