The Customers Won't Be Happy: How Atlassian Rolled Out a Large Scale UI Change for Confluence Cloud

In this March Meetup, Aaron Gentleman from Atlassian shared how his team tested in production during the rollout of ADG3 to Confluence Cloud. The team addressed three main concerns: whether the change was ready for customers, its impact on both customers and the company, and defining when they were done with testing. They used feature flags in LaunchDarkly to control risky changes and test new features in production. Key points include considering customer feedback, ensuring support readiness, and managing multiple code paths during testing. The team also emphasized the importance of keeping customers in mind while rolling out changes.
