What happens to historical data when a service is unmerged from a merged service?

When a service is unmerged from a merged service in Dynatrace, the historical data related to that service remains available for reference. This means that all past performance metrics, logs, and other relevant data pertaining to the unmerged service can still be accessed and reviewed. This feature is particularly useful in scenarios where understanding historical performance and trends is necessary for diagnosing issues or evaluating the impact of changes over time.

The ability to retain historical data upon unmerging supports effective monitoring and analysis, ensuring that users can continue to leverage this information for troubleshooting and performance optimization even after changes in service structure. This retention aspect is a significant advantage of the Dynatrace platform, as it fosters continuity and visibility into service performance, regardless of the organizational or structural changes that may occur.
