Your question is Zero-Downtime Migration Safeguards. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How have you approached migrating a high-throughput database or service with zero downtime at Render? What safeguards did you put in place?
Discuss how you would clarify migration requirements, preserve availability and correctness during the transition, validate the new path, and roll back safely. Cover traffic management, data consistency, observability, failure handling, and post-migration cleanup without assuming undocumented Render-specific infrastructure.
