You can validate a change set without deploying changes. Validating a change set allows you to view the success or failure messages you would receive with an actual deploy.
- From Setup, enter Inbound Change Sets in the Quick Find box, then select Inbound Change Sets.
- Click the name of a change set.
- Click Validate.
We recommend starting a validation during off-peak usage time and limiting changes to your org while the validation is in progress. The validation process locks the resources that are being deployed. Changes you make to locked resources or items related to those resources while the validation is in progress can result in errors.
- After the validation completes, click View Results.
Change sets that have been successfully validated might qualify for a quick deployment. For more information, see Quick Deployments.
