# Mergeability Rules and Merge Settings

Lifecycle Center blocks promotions if there’s a conflict, if a test failed, or if a mergeability rule or merge setting isn’t met.

Lifecycle Center honors the source control system’s mergeability rules and merge settings.

- Work items can be marked Ready to Promote only when the changes are deemed mergeable. Mergeability is determined either by merge conflicts or custom mergeability rules. If the source control system identifies merge conflicts with the changes, then the changes can’t be promoted until the conflicts are resolved.
- Similarly, if custom mergeability rules or merge settings haven’t been met for the changes, then the changes can't be promoted until those rules are met.

To improve release quality, we recommend you set up and use [DevOps Testing](https://help.salesforce.com/s/articleView?id=platform.devops_testing_improve_release_quality_with_devops_testing.htm&language=en_US).
