Occasionally, PingFederate introduces database-related changes, such as adding a new table, modifying an existing table, or updating the connection pool library, for the purpose of product improvement.
Neither the Upgrade Utility nor the PingFederate installer for Windows migrates data maintained in the internal HSQLDB database or any external database. For instance, if outbound provisioning is enabled in the new PingFederate instance using the internal database, it's re-initialized from the provisioning source.
Use the built-in HSQLDB only for trial or training environments. For testing and production environments, always use a secured external storage solution for proper functioning in a clustered environment.
