We’ve introduced a new feature that allows you to revert a schema change with no data loss.
If you create and deploy a deploy request with a schema change that breaks your application, you can instantly revert the deployment with the click of a button. Additionally, you’ll retain any data that was added to your production database during the time between deployment and reverting.
This feature is in limited beta and you must accept beta terms and enroll your database to use it. For more information, see the Revert a schema change section of our Deploy requests documentation.
