What is Update Sets?

Update Sets are a mechanism used in platforms like ServiceNow to group and migrate customizations and configurations between different instances. They capture changes made to the platform, such as new business rules, UI policies, or table configurations. Once an update set is completed, it can be exported and applied to another instance, effectively replicating the changes without manual recreation. This simplifies the deployment and maintenance of customizations across various environments (e.g., development, testing, production).
