What are the steps for applying an update set to an instance?

The correct sequence for applying an update set in ServiceNow is to Retrieve, Preview, and Commit.

Initiating the process begins with the Retrieve step, where the selected update set is brought into the current instance. This action gathers all the changes contained within that update set from the source instance.

Following retrieval, the Preview step allows administrators to analyze the incoming changes for potential conflicts or issues before applying them. This preview process is crucial because it helps ensure that the changes will not disrupt existing functionalities or overwrite critical data unintentionally.

Finally, the Commit step is the last action in applying the update set. During this phase, the changes are actually applied to the current instance, solidifying the updates and making them a part of the overall system configuration.

This sequence ensures a structured and safe approach to managing updates, reducing the risk of disruptions in the environment once the changes are finalized.
