Issue: After you upgrade from Provider Services Release 9.2.1 to Release 11.1.2.1, one or more clusters no longer exist.
This issue can occur if you had both High Availability Services and Smart View Provider in Release 9.2.1 and the domain.db files from those products had clusters with the same name, but the cluster components did not match.
Solution: See the aps-upgrade.log file for details, and use Administration Services Console to resolve the conflict.
