Legacy Migration Strategies
Choosing the right path for your business
đ Rehost (Lift & Shift)
Move legacy applications to modern infrastructure with minimal changes. Ideal for quick wins and immediate cost savings.
Best for: When you need to exit data centers quickly, or when applications are still valuable but infrastructure is obsolete.
đ Replatform (Lift & Optimize)
Make targeted changes during migrationâlike moving to managed databases or containerizationâwithout full rearchitecture.
Best for: When you want some cloud benefits without the cost and risk of full redesign.
⨠Refactor / Re-architect
Transform legacy applications into modern, cloud-native architecturesâmicroservices, serverless, etc.
Best for: When you need maximum agility, scalability, and innovation, and are willing to invest for long-term value.
đ Retire / Replace
Decommission obsolete applications and replace with modern SaaS solutions or COTS products.
Best for: When functionality is available in modern packages and customization needs are low.
Legacy Migration Challenges We Solve
Turning risks into opportunities
Legacy migrations are complex. Our expertise ensures we navigate the pitfalls and deliver successful outcomes.
Lost Business Logic
We use automated discovery and expert analysis to capture and preserve critical business rules.
Data Integrity
Rigorous validation, reconciliation, and testing ensure zero data loss or corruption.
Business Downtime
Parallel runs, phased cutovers, and fallback planning keep your business running.
Poor Documentation
We use code analysis and reverse engineering to understand undocumented systems.
Our Legacy Migration Process
Proven methodology for complex migrations
We combine automated tools with deep domain expertise to modernize even the most complex legacy landscapes.
Discovery & Assessment
We inventory legacy assets, analyze code and data, map dependencies, and identify business rules. We assess options and build a business case.
Strategy & Target Architecture
We define the migration approach (rehost, replatform, refactor), design the target architecture, and create a detailed roadmap.
Proof of Concept
We validate the approach with a pilot migration, test performance, and refine processes before scaling.
Migration Execution
We execute migrations in phases, with automated code conversion, data migration, and continuous validation.
Testing & Validation
We rigorously test functionality, performance, and integration. Business users validate results in UAT.
Cutover & Hypercare
We execute cutover, decommission legacy systems, and provide intensive post-migration support.

Frequently Asked Questions
Common questions about legacy system migration
Legacy system migration is the process of moving from outdated, often mainframe-based or obsolete technology platforms to modern systems. This can involve rehosting, replatforming, refactoring, or replacing legacy applications.
Key drivers include: high maintenance costs, security vulnerabilities, lack of skilled resources, inability to innovate, compliance risks, and the desire to leverage modern capabilities like cloud, AI, and real-time analytics.
We use code analysis tools, automated discovery, and work with your subject matter experts to extract and document business rules. We also use test cases to validate that behavior is preserved in the new system.
Timelines vary based on complexity, size, and chosen strategy. Simple rehosting can take months, while complex refactoring may take years. We break projects into phases to deliver value continuously.
We mitigate this through multiple validation steps, parallel runs, reconciliation, and fallback procedures. Our track record shows zero data loss in legacy migrations.
Yes. We specialize in migrating custom legacy applications built in COBOL, PL/I, RPG, PowerBuilder, Delphi, and many other languages to modern technology stacks.
