Enterprise Re-Platforming & Cloud Migration
Legacy Application Modernization Services
Break free from fragile desktop software, unmaintained frameworks, security vulnerabilities, and brittle Excel workarounds. We re-engineer legacy .NET, Classic ASP, FoxPro, and old PHP systems into cloud-native Laravel, React, and Node.js architectures with 100% data integrity and zero business interruption.

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.
Engineering Methodology
The Strangler Fig Migration Pattern
We reject high-risk "big bang" rewrites in favor of phased, zero-downtime micro-migrations.
Audit & Discovery
Reverse-engineering database schemas, stored procedures, third-party hooks, and user workflows. Documenting implicit business rules hidden inside legacy code.
Target Architecture
Designing clean relational schemas in PostgreSQL/MySQL, Dockerized microservices, REST/GraphQL API endpoints, and a modern reactive UI design system.
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.
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
Modernization Pricing & Engagement
Predictable project milestones or dedicated agile modernization squads.

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 routinely modernize legacy Microsoft .NET Framework (ASP.NET WebForms, MVC 2-4, WCF), Classic ASP (VBScript), Visual FoxPro (DBF databases), legacy PHP 5.2 - 7.2 (custom procedural code, Zend 1, CodeIgniter 2), Visual Basic 6 desktop applications, and fragile mission-critical Excel VBA macroeconomic workbooks into modern cloud-native architectures.
How does your timezone alignment work for global enterprises?
Flexible Timezone Alignment: Choose Dedicated Full-Shift Engineers working 100% in your local business hours (Americas, UK/EU, MEA, APAC, or Oceania) or Hybrid Overlap Squads for 24-hour development velocity. Legacy analysis, user acceptance testing (UAT), and cutover syncs happen directly during your team's workday.
Do we get 100% Day-1 IP and source-code ownership?
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.
