Codebase & Dependency Audit
We analyze your codebase, map package dependencies, and write a step-by-step upgrade plan.
Product Engineering
Modernize Legacy Systems Without Disrupting Your Business
We migrate legacy monolith databases, upgrade old PHP/jQuery frontends to React, and set up secure cloud server deployments.

— Modernization Services
Legacy Application Upgrades
We rewrite old codebase routes, migrate database schemas, and deploy updated backend API servers.
Server Route Deconstruction
We split large backend code bases into separate API servers, shifting traffic incrementally.
React & Frontend Migrations
We rewrite legacy jQuery and PHP HTML templates into fast, component-based React views.
Database Schema Upgrades
We write data migration scripts, convert database types, and safely transfer tables.
API Version Upgrades
We write backend routing layers to handle new API structures without breaking older integrations.
Docker & Server Automation
We package your app into Docker containers and configure automated test pipelines.
— Our Migration Methodology
Our Migration Process
1
Codebase & Dependency Audit
We audit package dependencies, profile database query speeds, and map current server routes.
Audit Report & Roadmap
Weeks 1–2
2
Architecture & Database Design
We design new database tables, draft the upgraded API endpoints, and map the transition steps.
Database Schema Diagrams
Weeks 2–3
3
Frontend & API Implementation
We code React components, rewrite API controllers, and run automated script comparisons on data output.
Functional Upgraded App
Weeks 3–12
4
Live Server Switch & Alerts
We switch domain traffic to new cloud servers, set up error alerts, and decommission legacy instances.
Production Monitored System
Weeks 12–14
What We Migrate To
Modern stacks, cloud-native architecture, and battle-tested tooling.
FAQs
Questions About Application Modernization
Answers to the questions every engineering leader asks before committing to a migration.
We use the strangler-fig pattern — new services are built alongside the legacy system, not instead of it. Traffic is shifted incrementally as each service is validated. The old system handles all requests until we are confident the new one is ready. We have never caused a production outage during a migration.
Almost always incrementally. Full rewrites are 3× more expensive, 2× as likely to be abandoned mid-project, and carry the risk of shipping a new system with the same architectural problems as the old one. Incremental migration lets you validate each piece before moving on.
A focused API or frontend modernization takes 6–10 weeks. A full monolith-to-microservices migration typically takes 12–20 weeks depending on codebase size and complexity. We scope precisely after the audit.
Yes — this is the whole point. We work on a separate branch or parallel service, and our changes do not block your team. We coordinate integration points carefully so both workstreams can proceed in parallel.
Every migration step has a documented rollback procedure before we execute it. We maintain the legacy code path until each new service has been in production for a defined validation period. Rolling back is a deliberate, tested option — not a panic measure.
We run data migrations with dual-write phases — writing to both old and new systems simultaneously — then validate consistency before switching reads to the new system. Historical data is migrated in batches with checksums to verify completeness.
Yes. We document every architectural decision, write comprehensive README files, record walkthrough videos, and run knowledge transfer sessions with your engineers. The goal is a system your team owns and understands, not one that only we can maintain.
Incremental modernization typically costs 40–60% of a full rewrite and carries a fraction of the risk. The audit phase alone often identifies quick wins that pay for the entire engagement in performance improvements or reduced hosting costs.
