Use the PingFederate SDK to implement a custom solution for client storage.
CAUTION:
PingFederate does not migrate client records from one storage medium to another. You must recreate your clients after updating the client storage configuration. If you need only a few clients, you can recreate them using the administrative console.
If you need a large number of clients, use the administrative API to retrieve your client records before updating the client storage. Update the client storage configuration and recreate your clients using the administrative API based on the retrieved records. For more information, see PingFederate administrative API.
