Overview
A century-old pediatric hospital system — one of the largest in the country — maintained a massive legacy analytics portfolio of 300+ applications spanning clinical and financial systems. The entire portfolio needed to be migrated to a modern platform under a hard deadline, but nobody had a systematic way to evaluate what they had, what mattered, and what could go. Evil Genius delivered the diagnostic framework, migration methodology, and team enablement to make it happen.
The Situation
The hospital system's legacy analytics portfolio had grown organically over many years — 300+ applications ranging from a few megabytes to 10 gigabytes, spanning both clinical and financial data systems. Many were highly customized and potentially over-engineered. There was no inventory, no complexity assessment, and no systematic process for evaluating what needed to be migrated, what should be rebuilt, and what could be retired. Complicating matters: a new hospital was opening in September 2024, and the full migration had a hard deadline of end of 2025. There was no room for false starts.
Our Approach
- 1
Assessed representative applications across the full complexity spectrum to establish patterns — from lightweight reports to multi-gigabyte, highly customized clinical analytics applications.
- 2
Developed a comprehensive migration framework with standardized complexity scoring, giving the organization a repeatable methodology for classifying every application by migration difficulty.
- 3
Built a triage methodology for prioritizing applications — which to migrate first, which to rebuild from scratch, and which to retire. Not every legacy application deserves a new life.
- 4
Created effort estimation guidelines calibrated to the organization's specific portfolio, along with step-by-step migration instructions and UI conversion best practices.
- 5
Delivered knowledge transfer sessions — two 90-minute deep reviews plus follow-up — ensuring the internal development team could execute the migration independently. Provided conversion tooling guidance for semi-automated migration of 60–70% of application metadata.
Results
- Comprehensive migration framework delivered covering all 300+ applications
- Standardized complexity scoring methodology — every application classified by migration difficulty
- Triage system established: migrate, rebuild, or retire for each application
- Effort estimation model calibrated to the organization's specific portfolio
- Internal development team enabled with methodology, documentation, and conversion tools
- Migration roadmap aligned with new hospital opening and hard end-of-2025 deadline
What This Made Possible
The hospital system went from '300+ applications and no idea where to start' to a clear, prioritized migration roadmap with the methodology and tools to execute it. The internal team now has a repeatable framework — not just a one-time plan. And the diagnostic-first approach ensured that migration resources go to the applications that matter, not the ones that should have been retired years ago. That's the difference between a migration that succeeds and one that just moves the mess to a new platform.
