In this course, you'll be able to explain the benefits of Worker Versioning, you'll configure Workers to participate in Worker Versioning, you'll evaluate tradeoffs to choose Versioning Behavior for Workflows, you'll discover how to use Temporal's routing system to control exactly which Workflows run on which Worker Versions. Finally, you'll explore the drainage process that lets you safely sunset old deployment versions by monitoring when all Workflows complete naturally, plus emergency remediation techniques for moving Workflows when critical issues arise.
