In Device Adapter Release 10.1.x, the Personal Directory data is stored in the Avaya Breeze® platform PPM for Data Privacy. Prior to Release 8.1.2, the Personal Directory data was stored in the Avaya Breeze® platform cluster database.

In Device Adapter Release 10.1.x, you must migrate the Personal Directory data from the cluster database of Device Adapter Release 8.1.1 and earlier to the PPM. For Data Privacy, you must delete the Personal Directory data from the cluster database. However, if you delete the Personal Directory data from the cluster database, you cannot downgrade Device Adapter from Release 10.1.x to 8.1.1 without losing the PD data.

For more information, see Migrating the Personal Directory data from Device Adapter 8.1.1 and earlier to 10.1.x.

Before downgrading Device Adapter from Release 10.1.x to 8.1.1, ensure that the call center agents are logged out of the CC phones.
