How should Universal Containers migrate new custom objects and workflows from a sandbox to the production environment?

Migrating new custom objects and workflows from a sandbox to the production environment is best accomplished using change sets. Change sets provide a user-friendly way to bundle and transport metadata components, such as custom objects and workflows, between Salesforce environments. This method helps maintain the integrity of configurations as it includes components with dependencies and ensures they are deployed in the correct order.

When using change sets, administrators can easily select the components they wish to include and send them to production without needing to manually duplicate efforts or risk discrepancies that may arise from manual recreation. This approach also allows for tracking of what has been deployed and simplifies collaboration among team members.

Other methods, such as using the data loader, are intended for migrating data rather than metadata. Therefore, they would not be suitable for moving custom objects or workflow configurations. Similarly, manually recreating configurations is prone to human error and inefficiencies. The option of clicking the Refresh Production button does not exist in Salesforce as a method for migration. Thus, utilizing change sets stands out as the most effective and standardized approach for this specific task.
