AI Case Studies in Practice: Remediating Post-Migration Data Inconsistency in Production
Business Context
After a high-risk database migration, production traffic was already running on the migrated instance when a severe inconsistency was discovered. Around 5 percent of all queries were failing, creating major business and operational risk.
Situation
The migrated database contained hundreds of tables and approximately 2 TB of data. A rollback was highly complicated because new production data had already been written.
Why it was hard
- Critical incident under live production load
- Immediate need to remediate about 4,000 urgent records
- Total inconsistency scope near 500,000,000 records
- Escalation pressure increased every hour
How we used AI
We assembled full context (logs, product documentation, and source code) and used AI to localize the root problem.
- Root cause area identified in about 20 minutes
- AI-generated hotfix ideas used for rapid triage
- AI-generated remediation scripts validated in test environments
- Three remediation strategies compared: documentation path, hotfix-derived path, and configuration-based bypass
Outcome
- Fast root-cause localization dramatically shortened diagnosis time
- Documentation-only approach failed and caused a short outage
- AI script for full production scope was too risky and slow
- Final fix implemented manually by experts and production stabilized in about 30 additional minutes
Delivery Impact - What this means for software delivery
AI provided substantial acceleration in diagnosis and option exploration, but final incident resolution still depended on expert decision making. This case demonstrates both the value and limits of AI in high-stakes production recovery.
What made the difference
- Complete technical context
- Testing predefined hypotheses against supporting and contradicting evidence
- Strict validation before production execution
- Willingness to override unsafe AI output
- Senior engineering expertise
AI accelerated understanding, but safe execution required human accountability and deep domain knowledge.
