Your question is Migrate to Microservices Zero Downtime. 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).

Problem

Explain how you would migrate a legacy component to a microservice architecture with zero downtime at Adobe.

Discuss how you would discover dependencies, define the service boundary, preserve API and data compatibility, and progressively move production traffic. Explain your deployment, observability, rollback, and validation strategy, including how you would handle dual writes, inconsistent data, schema changes, and failures during the transition. Assume the legacy component is business-critical and cannot tolerate planned downtime. Clarify any missing scale, availability, consistency, and compliance requirements before proposing the migration.
