Software Modernization

Modernization of existing software through targeted code, architecture, dependency, interface or infrastructure improvements while preserving required business functionality.

From $300 · 3-10 weeks

Overview

Modernization begins with an assessment of the current codebase, dependencies, infrastructure and known pain points, followed by a phased plan that avoids a risky all-at-once rewrite. Typical work includes upgrading outdated frameworks and runtimes, refactoring tightly coupled modules, adding automated tests around critical logic and moving deployment to containers or CI/CD. You receive the updated system, a record of changes made and a list of remaining technical debt.

Benefits

  • Supported frameworks and dependencies

  • Lower cost of future changes

  • Automated tests around critical logic

  • Phased changes instead of a full rewrite

What's included

  • Code audit
  • Modernization plan
  • Refactoring and updates
  • Testing and deployment

Typical use cases

  • The application runs on an unsupported framework or language version
  • Small changes take disproportionately long to implement
  • Original developers are no longer available
  • Manual deployments need to move to CI/CD
  • A monolith needs separation of specific modules

How it works

  1. Assessment of code, dependencies and infrastructure
  2. Phased modernization plan with priorities
  3. Test coverage for critical business logic
  4. Incremental refactoring and upgrades
  5. Verification, deployment and technical debt report

What we need from you

  • Access to the source code repository
  • Access to staging or a copy of the production environment
  • Description of business-critical functionality to preserve
  • Any existing documentation or architecture notes

Service FAQ

Changes are delivered in phases and tested in a separate environment before release, which keeps disruption to a minimum. Any release that needs a maintenance window is planned with you in advance.
