In this lecture, I take you through various pre-deployment and post-deployment concerns when deploying apps to various environments on the platform. I also introduce you to the Salesforce Development Lifecycle Guide. Some of the topics covered include the View Setup Audit Trail, the Deployed checkbox for custom objects, and activating workflows and processes during post-deployment. We also discuss the need for backing up data and getting legacy data in-sync with new changes to the platform via app deployments.
