How would you answer an interview scenario involving EF Core migrations in Entity Framework Core?

AdvancedUpdated 2026-08-09

For an interview scenario involving EF Core migrations, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Migrations capture model-driven schema changes as versioned database operations. For production, review generated SQL, test on production-like data, use backward-compatible rollout patterns, and back up critical data. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
