change sets are tools that allow administrators to move customizations from one Salesforce org to another. However, change sets do not track dependencies or conflicts between components in different orgs, so administrators need to manually verify that all required components are included in the change set and that they do not overwrite existing customizations in the target org. To avoid losing changes in production due to deploying an incomplete or incorrect change set, administrators should push the change set to another sandbox first and test it there before deploying it to production.
