What happens to the segment membership when a new default merge policy is applied to a sandbox?

When a new default merge policy is applied to a sandbox within Adobe Experience Platform, segments automatically switch to the new default policy. This is important because it ensures that all segments adhere to the most current rules and practices established by the updated merge policy. The automatic switch allows for seamless integration of the new policy, ensuring that data integrity and processing efficiency are maintained.

This feature is particularly useful as it reduces manual overhead and the potential for errors that could occur if segment membership needed to be updated manually or reviewed. Instead of locking segments, deleting them, or requiring manual reassignment, the automatic adjustment facilitates smoother operations and keeps the segments aligned with the latest guidelines without unnecessary interruptions.
