In which scenario should a restore of the PCE be executed?

Restoring the Policy Compute Engine (PCE) after an upgrade is a critical process to ensure that the system is functioning properly following significant updates. Upgrades may introduce new features, changes to existing functionality, or adjustments to system architecture. These changes can impact how policies are managed and enforced across the network.

In case something goes wrong during the upgrade process—be it due to a faulty update, configuration issues, or compatibility problems—having the ability to restore the PCE to its previous state is essential for maintaining network security and operational integrity. This restoration allows organizations to revert to a known good configuration where policies were functioning as intended, thereby minimizing downtime and disruption to services.

While user access scaling, network configuration changes, and system maintenance are important operational considerations, they do not necessitate restoring the PCE in the same manner an upgrade does. An upgrade typically poses increased risk due to the changes made, which is why a restore is applicable specifically after such a significant event.
