Abstract
Routine database upgrades should be straightforward, especially with familiar, well-established technology. We were confident heading into our Elasticsearch upgrade, equipped with a solid plan and excited to see performance gains like we had seen from past upgrades. But what started as a straightforward upgrade became a week-long catastrophe that brought our platform to its knees. For six grueling days, we fought cluster instability while our Fortune 500 customers demanded answers we didn't have.
This talk shares the raw story of struggle and how disaster became the greatest teacher. The experience highlighted how creating psychological safety, leveraging community support, exceptional leadership, and team character can often matter more than technical solutions. You'll take away six hard-won lessons that will better prepare you for when your next "routine" upgrade goes sideways.
