Lift-and-Shift Is Not Modernization.
Let Us Do This Right.
Lifting a 20-year-old application to the cloud does not make it a cloud application. It makes it an expensive 20-year-old application. True legacy modernization unlocks the business value trapped in aging systems: agility, scalability, integration capability, and access to modern services like AI. 51% of IT spending is moving to cloud. The organizations getting real value are the ones who modernize, not just migrate.
Discuss Legacy ModernizationThe Challenge
The Technical Debt Trap
Legacy systems are often your most critical applications. They run core business processes. But they are also your biggest constraint. Cannot integrate with modern tools. Cannot scale for new opportunities. Cannot find developers who know the technology. Lift-and-shift seems attractive because it is "faster," but you just move technical debt to the cloud where it is even more expensive to maintain. Eventually, you have to modernize. Why not do it right the first time?
Our Approach
We help you modernize strategically. Not everything needs to be rewritten. Some applications are fine to rehost. But for core systems that will drive your business for the next decade, we design modernization approaches that unlock real value: API-enabled integration, cloud-native scalability, modern UX, and maintainable codebases. We preserve your business logic while replacing the technical constraints.
What We Deliver
Capabilities
Legacy Assessment
Evaluate legacy applications for modernization potential. Business value, technical complexity, and modernization ROI analysis. Know what is worth modernizing and what to retire.
Modernization Strategy
Define the right approach for each application: retain, retire, rehost, replatform, refactor, or replace. Strategic roadmap with clear decision rationale.
Mainframe Modernization
COBOL, AS/400, and mainframe modernization. Preserve decades of business logic while enabling cloud capabilities. We have engineers who understand legacy technology.
Application Refactoring
Decompose monoliths into microservices. Modernize architecture while preserving functionality. Incremental transformation, not big-bang rewrites.
Database Modernization
Migrate legacy databases to cloud-native platforms. SQL Server, Oracle, DB2 to cloud alternatives. Data quality improvement during migration.
Integration & APIs
Expose legacy functionality through modern APIs. Enable integration with SaaS, mobile, and AI without full replacement. Sometimes the best modernization is enabling integration.
Our Process
How We Work
Discover & Assess
Inventory legacy applications. Evaluate business criticality, technical debt, and modernization complexity. Map dependencies and business logic.
Strategy & Prioritization
Define modernization approach by application. Sequence for business value and dependency management. Build the business case.
Architecture Design
Target architecture for modernized applications. API strategy, data architecture, security model. Design for the next decade, not the next quarter.
Iterative Modernization
Incremental modernization with continuous delivery. Working software throughout transformation. No 18-month silence followed by a big reveal.
Retire Legacy
Decommission legacy systems as modernization completes. Documentation and knowledge transfer. Clean break from technical debt.
Why Flynaut
What Makes Us Different
Business Logic Preservation
Your legacy systems contain decades of business rules. We extract and preserve that value. You do not lose what makes your business work.
Incremental Approach
Big-bang modernization fails. We deliver working software throughout the transformation. Value at every phase, not just at the end.
Mainframe Experience
We have modernized COBOL, AS/400, and ancient systems others will not touch. Our team includes engineers who understand legacy technology and speak its language.
Security Through Modernization
Legacy systems often have security vulnerabilities that cannot be patched. Modernization is a security improvement. Our cybersecurity team validates that the modern version is more secure than what it replaces.
Results
Insurance Company Modernizes 25-Year Policy System, Saves $2M Annually
A regional insurer's policy management system was written in COBOL on AS/400. Only 2 developers (both nearing retirement) could maintain it. New product launches took 6+ months. Extracted business rules into modern microservices architecture on AWS. Preserved policy logic while enabling API integration. Phased migration with parallel running.
Results are illustrative, inspired by real client engagements. Specific metrics pending client verification.
