Explanation
Change Sets are the deployment solution that a consultant should use to move an updated Service Console from a sandbox to Production. Change Sets are collections of metadata components that can be deployed from one Salesforce org to another. Change Sets can be used to deploy the configuration settings for the Service Console, such as the app definition, the page layouts, the tabs, the components, the utility bar, or the navigation rules. Change Sets can also be used to deploy other related components, such as objects, fields, profiles, permissions, workflows, or reports.
