What is required for a successful PCE migration?

A backup from the previous version of the PCE software is essential for a successful PCE migration because it ensures data integrity and continuity during the migration process. When transitioning to a new version or instance of Illumio's Policy Compute Engine (PCE), having a backup allows administrators to restore existing configurations, policies, and historical data if needed. This precaution mitigates the risk of data loss or misconfiguration that could occur during the upgrade.

In addition, the backup provides a clear reference point to compare against after migration, confirming that all necessary components and settings have been successfully transitioned to the new environment. It is a critical step to safeguard against unexpected issues that may arise during the migration process.
