Legacy Website Modernization TeamModernization Team
We rebuild your legacy site on modern stacks like Next.js and Headless CMS. 8-12 week delivery, fixed price, no surprises.
IRPR is a legacy website modernization team that replaces outdated stacks (jQuery, PHP, monolithic CMS) with modern frameworks like Next.js, Gatsby, or Astro. We migrate content to headless CMS platforms (Contentful, Strapi, Sanity) and deploy on AWS or Vercel with CI/CD pipelines.
Every project ships in 8-12 weeks with a fixed price starting at $80K. We handle compliance needs like HIPAA, PCI-DSS, and SOC 2. You get full source code ownership, automated testing, and a 99.9% uptime SLA.
Our buyers are CTOs at SaaS companies migrating from a legacy monolith, marketing directors at ecommerce brands needing a faster, SEO-friendly site, and operations VPs in healthcare moving away from a 10-year-old Drupal install.
Types of software we ship.
Headless CMS migration
Migrate from WordPress/Drupal to Contentful or Strapi. Decouple frontend from backend for faster edits and better performance.
Monolith to micro-frontend
Break a single large codebase into independently deployable frontend modules. Use Module Federation with Webpack 5.
Static site regeneration
Convert a dynamic PHP site to a statically generated Next.js site. Pre-render pages at build time for 10x faster load speeds.
Legacy API modernization
Replace SOAP or REST v1 APIs with GraphQL or REST v2. Add OpenAPI specs and automated integration tests.
Cloud migration for websites
Move from on-prem servers to AWS or Azure. Set up auto-scaling, CDN via CloudFront, and automated backups.
Accessibility compliance rebuild
Audit and rebuild a legacy site to meet WCAG 2.1 AA standards. Fix keyboard navigation, screen reader support, and contrast ratios.
Performance optimization overhaul
Reduce Core Web Vitals scores from poor to good. Implement lazy loading, image optimization (WebP), and code splitting.
Legacy ecommerce re-platform
Migrate from Magento 1 or custom PHP cart to Shopify Plus or Next.js Commerce. Preserve order history and customer accounts.
We build for every business type.
SaaS companies
Healthcare organizations

Why your legacy website needs a modernization team
A legacy website costs you money in lost traffic, slow load times, and security risks.
A site built on jQuery or PHP 5.x loads 3-5 seconds slower than a modern Next.js site. That delay drops conversion rates by 20% on average. Google's Core Web Vitals update in 2021 penalizes slow sites in search rankings. A legacy website modernization team fixes this by rebuilding on a static or server-rendered framework.
Security is another reason. Old CMS versions like Drupal 7 or WordPress 4.x have known vulnerabilities. IRPR migrates your site to a headless CMS with automatic security patches and role-based access. We also add HTTPS enforcement, CSP headers, and automated vulnerability scanning.
The difference between a generic dev shop and a legacy website modernization team
Not every agency can handle the complexity of migrating a 10-year-old codebase.
Generic shops often start coding without a migration plan. They miss edge cases like custom plugins, 3rd-party integrations, or old database schemas. IRPR begins with a 2-week Roadmap phase where we audit your entire stack, map dependencies, and write a detailed migration plan with a fixed price.
We also handle the messy parts: migrating user sessions, preserving SEO rankings with 301 redirects, and maintaining uptime during cutover. Our team has done this for 200+ sites across healthcare, fintech, and ecommerce.
- No upfront audit of your legacy codebase
- Hourly billing with no fixed estimate
- No SEO migration plan (loses rankings)
- One-size-fits-all tech stack
- No compliance review (HIPAA, PCI)
- Handoff with no documentation
- 2-week Roadmap phase with full audit
- Fixed price from week 2 onward
- 301 redirects and SEO preservation plan
- Tech stack chosen for your specific needs
- Built-in HIPAA, PCI-DSS, SOC 2 compliance
- Full documentation and CI/CD pipeline
How IRPR modernizes your legacy website in 4 phases
Our process moves from audit to deployment with clear milestones.
Phase 1: Roadmap. We audit your current tech stack, identify technical debt, and map all dependencies. You get a detailed plan with a fixed price and timeline. This takes 2 weeks.
Phase 2: Build. Our team rebuilds your site on the new stack. We set up a headless CMS, migrate content, and implement the new frontend. You see progress in bi-weekly demos.
What ships with every legacy website modernization project
You get more than a new site. You get a production-ready system.
Every project includes a complete handoff package. No knowledge gaps, no black boxes. Your team can take over immediately.
- Full source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Vercel
- Headless CMS setup (Contentful, Strapi, or Sanity)
- Automated end-to-end tests with Cypress
- SEO migration report with 301 redirect map
- Performance audit showing Core Web Vitals scores
- Security audit with HTTPS, CSP, and vulnerability scan
- Deployment runbook and architecture documentation
- 30-day post-launch support with priority bug fixes
- Sentry error tracking and Datadog monitoring
