AI-accelerated SQL Server → MySQL reporting modernization
Situation
A reporting estate built over many years on SQL Server — including stored procedures, SSRS reports, subscriptions, schedules, SSIS packages, and SQL Agent jobs — needed to move to MySQL 8 without changing the business meaning or output of hundreds of reports. The scale and dependency complexity made a manual rewrite approach too slow, inconsistent, and difficult to validate safely.
Approach
- Built an AI-assisted migration factory that inventories stored procedures, functions, views, reports, packages, schedules, and downstream dependencies across the reporting estate.
- Used specialized AI agents to analyze source logic, extract business intent, map dependencies, generate MySQL-compatible rewrites, identify unsupported SQL Server patterns, and surface high-risk conversion decisions for human review.
- Established a governed lifecycle for every object: discovery, dependency resolution, intent extraction, rewrite, validation, exception review, approval, and release.
- Created a dedicated QA harness that generates representative test cases and compares SQL Server and MySQL results row by row, preventing syntactically correct but functionally wrong rewrites from being approved.
- Applied human approval gates to parity exceptions, architectural changes, and production-impacting decisions rather than allowing autonomous promotion.
- Extended the migration beyond stored procedures to include SSRS delivery, subscriptions, SSIS dependencies, SQL Agent workflows, environment synchronization, and cutover planning.
Where it stands
AI transformed the effort from a sequence of manual rewrites into a controlled modernization program. A prioritized queue of more than 300 reports and procedures now moves through a repeatable factory cadence, with business intent preserved, dependencies documented, and output parity proven before approval. The result is faster delivery without sacrificing engineering control: AI performs the high-volume analysis and conversion work, while experienced database oversight governs architecture, risk, validation, and final acceptance.
Verification
Object counts come from the migration factory's tracking inventory; parity is proven per object by a harness comparing source and target result sets row by row, with human sign-off gating approval.
Limitation
The migration is in progress — figures describe the working queue and validated objects, not a completed cutover.
