How Ideas2IT Used Legacyleap to Match AEA Growth's Aggressive Modernization Timeline for AS Software

AS Software had spent 30 years building the ultrasound reporting platform that over 35% of US healthcare enterprises run on. When AEA Growth invested with aggressive plans to scale, the technology was the blocker: half the platform was on-prem, slow, and unstable, and AEA needed it modernized fast with AI. Ideas2IT used Legacyleap to rewrite 3 million lines of code in 7 months.

01 Challenge

AS Software was winning the market but the technology couldn't keep pace. Every customer ran a dedicated on-prem or Azure VM instance, onboarding took 3 weeks per tenant, and the VB6 and .NET 4.7.2 monolith had no API layer and no path to scale. AEA needed aggressive modernization, not a multi-year program.

02 Solution

Ideas2IT deployed Legacyleap to compress years of modernization into 7 months. All VB6 integration services were rewritten as .NET 8 microservices, Legacyleap scaffolded modular REST APIs from the existing monolith, and 290 customer environments were migrated from Azure VMs and on-prem to a schema-per-tenant AWS architecture with zero downtime.

03 Outcome

Tenant onboarding dropped from 3 weeks to under a day, infrastructure costs fell 65%, and development velocity increased 3x. AS Software went from a technically stalled monolith to a cloud-native SaaS platform in 7 months.

Phase 01

Using AI to compress years of modernization work into months

Legacyleap Codebase Analysis and Migration Strategy

Before a single line was rewritten, Legacyleap analyzed the full codebase, mapped every dependency, and generated the refactoring blueprints that made 7-month delivery possible.

‍

  1. Legacyleap automated discovery across the VB6 and .NET 4.7.2 monolith, generating dependency maps and refactoring blueprints in days rather than months
  2. Zero-downtime migration strategy designed with parallel running of legacy and new services throughout cutover
  3. Multi-tenant AWS architecture blueprint replacing 290 single-tenant deployments with schema-per-tenant data isolation and RBAC enforcement
This phase produced
  • LegacyLeap codebase analysis
  • Dependency mapping
  • Zero-downtime migration strategy
  • Multi-tenant AWS architecture blueprint

Phase 02

From VB6 monolith to .NET 8 microservices, 290 environments to one platform

Microservices Rewrite and SaaS Migration

Legacyleap scaffolded the REST API layer while the team rebuilt every VB6 service as a containerized microservice and migrated all 290 environments to AWS without a single production outage.

  1. All VB6-based HL7, Fax, and DICOM services rewritten as containerized .NET 8 microservices with API-first design
  2. Legacyleap scaffolded modular REST APIs from the .NET monolith, reducing development effort by 40%
  3. 290 customer environments migrated to AWS with automated CI/CD, ECS orchestration, and zero-downtime cutover
This phase produced
  • .NET 8 microservices
  • Legacyleap REST API scaffolding
  • Schema-per-tenant multi-tenant SaaS
  • AWS migration of 290 environments
  • Automated CI/CD and ECS
  • Zero-downtime cutover

Phase 03

Rebuilding the interface that 8,000 clinicians use daily

Frontend Rebuild and Clinical UX

Ideas2IT rebuilt the full frontend in React, delivering 2x faster navigation and cutting onboarding time by 40% across the platform.

  1. React rebuild with React Hook Form and Redux Query delivering 2x faster navigation and deep linking across clinical workflows
  2. Modular component architecture enabling rapid feature deployment without destabilizing existing workflows
  3. Onboarding and training time cut 40% through improved usability and accessibility
This phase produced
  • React frontend
  • React Hook Form and Redux Query
  • Deep linking
  • Modular component architecture
  • 40% reduction in onboarding time
Development Modernization AWS Tools
.NET 8 / C# Legacyleap ECS, EC2, RDS Jenkins
React / Redux VB6 to microservices API Gateway, IAM Docker
REST APIs HL7, DICOM, Fax S3, CloudWatch Terraform
SQL Server Schema-per-tenant Secrets Manager SonarQube

hen AEA Growth invested in AS Software, we needed the technology to move as fast as the business plan. Ideas2IT used Legacyleap to deliver the most aggressive modernization schedule we had ever seen, and they delivered it without breaking a single customer deployment.

The Outcome

Category Metric Description
Modernization timeline 7 months 3 million lines of code, full platform rewrite
Tenant onboarding 3 weeks to under 1 day Via multi-tenant SaaS consolidation
Deployments consolidated 290+ into 1 Single multi-tenant platform on AWS
Infrastructure costs 65% reduction Cloud-native multi-tenant architecture
Development velocity 3x faster Post-modernization feature delivery
LegacyLeap impact 40% less dev effort AI-accelerated scaffolding and refactoring
Compliance HIPAA Maintained across all tenant environments
AS Software's platform now runs on architecture Ideas2IT rebuilt in 7 months using Legacyleap. AEA Growth came in with aggressive plans to scale a 30-year market leader and needed the technology to match that ambition fast. Three million lines of code, 290 deployments consolidated into one, and a cloud-native SaaS platform delivered on the most aggressive modernization timeline AS Software needed.
