Legacy Website Modernization ServicesModernization Services
We rebuild outdated websites in 8-12 weeks. Your new site ships with CI/CD, cloud hosting, and full source code ownership.
IRPR builds legacy website modernization services for companies stuck on old tech stacks like jQuery, PHP 5, or ColdFusion. We rewrite them with React, Next.js, Node.js, and Docker for cloud-native hosting on AWS or GCP.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle full cloud migration, set up CI/CD pipelines on GitHub Actions, and ensure compliance with SOC 2, HIPAA, or PCI-DSS if needed.
We work with CTOs who need to deprecate a monolith, engineering leads who want to reduce page load time by 60%, and product owners who require a modern developer experience with automated deployments and error tracking via Sentry.
Types of software we ship.
Static site rebuild
Convert legacy PHP sites into static Next.js sites with ISR for 10x faster load times.
Headless CMS migration
Move from WordPress or Drupal to a headless CMS like Sanity or Contentful with a decoupled frontend.
API gateway upgrade

Why legacy website modernization matters
Old websites slow down your business operations and frustrate users.
Legacy websites built on jQuery or PHP 5 typically have page load times above 5 seconds. IRPR rewrites them with Next.js and static generation, achieving sub-second loads and a 40% improvement in user retention.
Security vulnerabilities in outdated frameworks like ColdFusion or old WordPress plugins lead to compliance failures. IRPR migrates to modern stacks with automatic security patches and SOC 2 compliance built into the CI/CD pipeline.
What sets IRPR apart from generic dev shops
Most agencies treat modernization as simple tech swaps. IRPR treats it as a full product rebuild with zero downtime.
IRPR works directly with your team to map every endpoint, database procedure, and third-party integration before writing a single line of code. This eliminates the risk of missing critical business logic.
We deliver a complete CI/CD pipeline, cloud infrastructure as code (Terraform), and automated tests covering 85%+ coverage. You own the entire codebase and infrastructure definition after handoff.
- Uses hourly billing with no fixed price
- Often skips documentation of legacy system
- Delivers code without CI/CD setup
- Ignores SEO redirects and 404 handling
- No performance benchmark before and after
- Handoff leaves team with no runbooks
- Fixed price from $80K with no surprise invoices
- Detailed legacy system audit before migration
- Delivers CI/CD with GitHub Actions and Sentry
- Set up 301 redirect map and sitemap for SEO continuity
- Publish before/after Lighthouse scores (target 90+)
- Provide runbooks and 1-hour post-launch support
Our legacy modernization process
We follow a predictable 5-phase process that keeps your business running during the migration.
Phase 1: Audit and mapping. IRPR reverse-engineers your legacy codebase, documents all APIs and database schemas, and identifies dead code and security risks. This takes 1-2 weeks.
Phases 2-4: Build, test, and deploy. We write the new code in parallel with the old system, run integration tests, and perform a staged rollout with canary deployments to production.
Every modernization includes these deliverables
You get a turnkey modern application, not a half-done rewrite.
IRPR ships everything needed to run, deploy, and maintain your new site. No hidden costs for infrastructure setup or training.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and auto-deploy
- Cloud infrastructure as code (Terraform on AWS)
- Sentry error tracking and logging setup
- Automated unit and integration tests (85%+ coverage)
- SEO 301 redirect map and XML sitemap
- Performance audit with Lighthouse score targets (90+)
- Deployment runbook with rollback instructions
- 1 hour of post-launch support for your team
What we ship in this practice.
Healthcare portal migration
