Home / Case Studies / Modernizing a Legacy Database with AI for Stride
Stride's legacy database was the anchor dragging their entire engineering org. Queries ran for minutes. Environment syncs failed routinely. Feature releases stalled sprint after sprint. RTS Labs used AI-assisted schema analysis and automated migration tooling to complete what would have been a 4-month migration in 3 weeks — with zero data integrity issues and an 80% improvement in query performance.

Stride’s engineering team had been living with a performance problem they couldn’t outrun. The company’s legacy database — built fast in the early days and never properly restructured — had become the bottleneck for everything. Queries that should return in seconds were routinely taking four minutes or more. Complex analytics reports couldn’t run during business hours without impacting production stability. And with the schema undocumented and inconsistently structured after years of ad hoc changes, no one on the team fully understood what they were working with.
The downstream effects were compounding. Three out of four engineering sprints in the prior quarter had been delayed by database-related issues — either performance problems that required hotfixes, or sync failures between environments that forced manual rollbacks. The team was firefighting instead of building. New feature development had effectively stalled, and with competitors shipping faster, leadership knew the database issue had crossed the line from technical debt to strategic risk.
A traditional migration project was estimated at 16+ weeks — months of engineer time spent on manual schema analysis, script writing, and data validation before a single line of production data moved. Stride needed a faster path.
Core business queries were averaging 4+ minutes — slow enough that reports couldn’t run during business hours without degrading production performance. Engineers were scheduling complex queries for off-hours just to avoid the impact.
Data syncing between production, staging, and development environments was failing 23% of the time — requiring manual intervention, rollback procedures, and hours of engineer time to reconcile. Every failed sync was a tax on velocity.
Database performance issues delayed 3 of 4 engineering sprints in the prior quarter, forcing the engineering team into constant, daily firefighting. The backlog of features waiting on a stable, performant data layer actively stalled product velocity.
RTS Labs came in with a different frame: instead of treating this as a migration project, they treated it as an AI co-development problem. Rather than assigning engineers to manually reverse-engineer the schema, document relationships, and write migration scripts by hand, the RTS team used LLM-assisted analysis to do in 3 days what would have traditionally taken 3 weeks — producing a complete schema map, normalization recommendations, and a draft PostgreSQL migration plan before a single human script was written. That pace set the tone for everything that followed.
Deployed an LLM-powered schema analyzer that ingested the existing database structure, mapped foreign key relationships, identified normalization violations, and flagged data quality issues across every table. Produced a complete current-state schema map and a prioritized normalization plan in 3 days — compressing what is typically a 3-week manual process.
Used the schema analysis output to auto-generate PostgreSQL migration scripts covering table restructuring, data type normalization, index redesign, and constraint enforcement. Each script was validated against a staging replica before touching production — catching edge cases early with zero manual scripting required for the first pass.
Designed a dbt-powered ETL pipeline to clean, transform, and transfer data from the legacy system to the new PostgreSQL architecture. Implemented incremental load logic and data validation checkpoints at each stage, allowing production to remain live throughout the migration with automated integrity verification at completion.
Post-migration, RTS Labs ran a full query performance audit across Stride's highest-traffic endpoints. Redesigned index strategy, rewrote bottleneck queries, and configured AWS RDS monitoring with automated alerting for query time regressions. Delivered documented runbooks so Stride's engineering team could maintain performance independently.
