Legacy Stacks Replaced

Systems We Re-Platform into Modern Web Cloud

We reverse-engineer undocumented legacy codebases and safely migrate them into maintainable cloud architectures.

Legacy .NET & Classic ASP

Migrating aging ASP.NET WebForms, WCF services, and VBScript Classic ASP portals to clean Laravel/React architectures, liberating teams from obsolete Windows Server 2008/2012 VMs.

Old PHP (5.x - 7.x) & Spaghetti Code

Refactoring unmaintained custom procedural PHP, CodeIgniter 2, or Zend 1 monoliths into modern Laravel 11/12 with typed models, automated Pest/PHPUnit tests, and PSR-12 coding standards.

Visual FoxPro & Desktop Access DBs

Extracting corrupted or locked DBF/MDB database files, cleaning historical character encoding artifacts, and loading normalized relational tables into enterprise PostgreSQL or MySQL.

Fragile Excel & VBA Spreadsheets

Transforming mission-critical, formula-heavy corporate spreadsheets and unstable macros into multi-user web portals with validation rules, audit logging, and automated calculations.

Legacy Desktop Client-Server ERPs

Replacing thick-client desktop apps (VB6, Delphi, MFC) with responsive web-based ERP and CRM portals accessible from any browser, tablet, or smartphone without Citrix or VPN friction.

Security & Compliance Rectification

Resolving severe legacy vulnerabilities (SQL injection, cleartext password storage, lack of MFA, unpatched CVEs) with modern Argon2 hashing, OAuth2/SAML SSO, and SOC2-compliant logging.

End-to-End Capabilities

Core Modernization & Migration Capabilities

From legacy desktop binaries to cloud-native microservices, we engineer resilient bridges between historical business logic and modern scalable web architectures.

Desktop-to-Web Application Re-Engineering

Transform Windows desktop applications (VB6, VB.NET, WinForms, WPF, Delphi, FoxPro) into modern web applications accessible from any browser on any device. We preserve your business logic, user workflows, and data integrity while delivering modern UI/UX, multi-user concurrent access, role-based security, and cloud-native deployment — eliminating the pain of local installations, version conflicts, and single-machine dependencies.

Database Schema Cleansing & Migration

Audit, cleanse, and migrate databases from any source (SQL Server, Oracle, MySQL, MS Access, FoxPro, dBASE, flat files) to modern cloud-native databases. We normalize denormalized schemas, eliminate orphaned records, resolve encoding issues, establish proper foreign key relationships, and build automated ETL pipelines with row-level validation checksums to guarantee zero data loss during migration.

API Layer Creation & Legacy System Wrapping

Even before a full rewrite, we can wrap your legacy system with a modern REST or GraphQL API facade. This unlocks your legacy data and business logic for modern frontends, mobile apps, third-party integrations, and BI tools — effectively extending the life and reach of your existing investment while you plan full modernization at your own pace. The Strangler Fig pattern lets you replace legacy modules incrementally.

UI/UX Overhaul & Modern Interface Design

Legacy applications typically have dense, unintuitive interfaces built for obsolete low-resolution screens. We redesign the entire user experience with modern responsive layouts, clean typography, contextual navigation, keyboard shortcuts for power users, mobile-responsive views, and progressive disclosure patterns that reduce cognitive load while preserving workflows your team already knows.

2. Legacy LAMP / WAMP Monolith Refactoring

PHP 5.x Monolith → Modern Laravel 12

Legacy Trapped Architecture

  • Frameworks: End-of-life PHP 5.2 - 7.4, raw procedural PHP scripts, CodeIgniter 2/3, Smarty, CakePHP 1/2, or heavily hacked WordPress/Drupal cores
  • Architecture: Global variables, mixed HTML/SQL/PHP in single files, missing ORMs, and zero automated testing
  • Database: Unindexed MySQL 5.5 / MariaDB tables with MyISAM storage engines and unescaped query concatenations
  • Pain Points: Critical unpatched CVEs, rampant SQL injection vulnerabilities, complete developer lock-in, and server crashes during traffic spikes

Target Modern Architecture

  • Target Stacks: Modern Laravel 12 + Filament PHP v3 admin panels, or reactive Vue.js / React with Inertia.js (VILT Stack)
  • Runtime & Performance: PHP 8.3+ with Laravel Octane, FrankenPHP, or Swoole for high concurrency
  • Database & Caching: InnoDB / PostgreSQL with strict migrations, Redis caching, and automated queue workers

3. Aging Java EE & Legacy Desktop Systems

JSP / Desktop / Excel → Cloud Multi-Tenant ERP

Legacy Trapped Architecture

  • Legacy Systems: Aging Java EE (JSP, Servlets, Struts 1/2, EJB on Tomcat / WebLogic), Visual Basic 6, Visual FoxPro, MS Access, and multi-sheet VBA Excel macros
  • Storage & Formats: Corruptible .DBF, .MDB, or locked local spreadsheet files with zero simultaneous multi-user locking
  • Deployment: Heavy client-side desktop software requiring manual workstation installations and fragile VPN tunnels
  • Pain Points: Silent spreadsheet formula corruption, zero audit trails, inability to work remotely, and severe key-person dependency

Target Modern Architecture

  • Target Stacks: Cloud-native, multi-tenant web ERP portals built on modern Laravel 12 or Node.js with responsive React frontends
  • Data Extraction: 100% data fidelity extraction via idempotent ETL scripts with row-level SHA-256 hash validation

  • Business Value: Zero desktop client installations, instant real-time multi-branch collaboration, and seamless mobile access from anywhere

Engineering Methodology

The Strangler Fig Migration Pattern

We reject high-risk "big bang" rewrites in favor of phased, zero-downtime micro-migrations.

01

Audit & Discovery

Reverse-engineering database schemas, stored procedures, third-party hooks, and user workflows. Documenting implicit business rules hidden inside legacy code.

02

Target Architecture

Designing clean relational schemas in PostgreSQL/MySQL, Dockerized microservices, REST/GraphQL API endpoints, and a modern reactive UI design system.

03

Dual-Run Data Sync

Deploying bidirectional data sync or CDC event streams. The new system runs alongside the old one, verifying data calculations and transaction totals in parallel.

04

Zero-Downtime Cutover

Switching traffic by business unit or user role during an off-peak maintenance window. Rollback contingencies in place. Decommissioning legacy servers permanently.

Transparent Investment

Technical Clarifications

Frequently Asked Questions

How do you guarantee zero data loss during legacy migrations?

We execute a rigorous 4-stage data preservation pipeline: 1) Automated schema reverse-engineering with column-level parity mapping, 2) Idempotent ETL scripts with cryptographic hash checksum validation (MD5/SHA-256) matching source and target row counts, 3) Dual-entry staging runs where both legacy and target databases operate concurrently, and 4) Complete dry-run cutovers verified against historical audit trails before production decommission.

What legacy stacks do your modernization engineers specialize in replacing?

We modernize three dominant legacy categories: 1) Classic Microsoft/WISA Stack (ASP.NET WebForms, Classic ASP, VB.NET, IIS, SQL Server stored-proc monoliths) to modern Laravel/Next.js/.NET Core & cloud PostgreSQL; 2) Legacy LAMP/WAMP Monoliths (PHP 5.x/7.x, procedural PHP, CodeIgniter, CakePHP, old WordPress/Drupal hacks) to clean Laravel 12 + Filament PHP / Vue / React; and 3) Aging Java EE & Desktop Systems (JSP/Servlets, VB6, FoxPro, MS Access, multi-sheet Excel macros) to cloud-native multi-tenant web ERPs with 100% data fidelity.

How does your timezone alignment work for global enterprises?

Our modernization squads schedule active engineering reviews, legacy system analysis, and User Acceptance Testing (UAT) sessions to coincide directly with your business hours, while executing critical database cutovers and parallel-run syncs during low-traffic off-peak windows to guarantee zero operational downtime.

Who owns the refactored source code and architecture IP after legacy modernization?

Yes, 100%. All modern application source code, Docker container configurations, CI/CD pipelines, and automated migration scripts are committed directly to your private repositories from Day 1 under a mutual non-disclosure agreement (NDA) with zero recurring vendor licensing fees.

What is the typical timeframe and cost structure for a legacy modernization project?

Modernization projects typically range from 8 to 24 weeks depending on database complexity and business logic density. Costs range from $9,500 - $35,000 (USD) or ₹7,00,000 - ₹28,00,000 (INR) under fixed-scope milestones or monthly dedicated sprint squads, backed by guaranteed milestone acceptance criteria.
