Legacy Code Safety Net: Automated Refactoring & Regression Testing Service

A specialized technical services firm that deploys embedded teams into federal agencies for 6-12 month engagements to safely refactor legacy code using automated testing, staged migrations, and real-time monitoring. The service includes custom test harness generation, dependency mapping, and rollback automation—turning risky rewrites into low-risk, incremental improvements without system downtime.

SERVICE

48 weeks • 70% confidence

Value Proposition

Reduces modernization risk from 40-60% failure rate to <5% by using proven refactoring patterns and continuous validation; cuts timeline by 40% vs. big-bang rewrites; agencies avoid the $12M+ contractor lock-in by building internal capability; provides fixed-price, outcome-based contracts instead of T&M billable hours.

Target Audience

DoD, VA, SSA, and other federal agencies with COBOL/Mainframe/legacy Java systems running critical operations; CIOs and Program Managers with $2-8M modernization budgets

Key Features

  • Automated test harness generation from legacy system behavior (record-and-replay testing)
  • Dependency graph visualization and safe decoupling strategies
  • Staged refactoring with real-time canary deployments to production
  • And more, with full implementation detail...

Tech Stack

COBOL/Mainframe expertise (hire or partner with legacy shops) Java/Spring refactoring patterns (internal expertise) Test automation frameworks (JUnit, Selenium, custom record-replay tools) Static analysis tools (SonarQube, Checkmarx, Fortify)

Original Problem

Legacy government software systems are expensive and difficult to modernize without disrupting critical operations

Government agencies struggle to modernize outdated software infrastructure while maintaining operational continuity, leading to massive budget allocations ($12M+) to specialized contractors. Current solutions fail because legacy systems are deeply integrated into mission-critical workflows, making in-house modernization risky and time-consuming. Agencies lack internal expertise and tools to safely migrate, refactor, and enhance decades-old codebases without downtime or security vulnerabilities.
