Metatech Migration Works from TXP
Automated, Risk-Reduced Conversion of Gen (formerly CA Gen) to Native Architectures
Migrate your Gen platform with our advanced migration toolset
Many organisations still rely on Gen (formerly CA Gen) applications to run mission-critical systems. But the challenges of maintaining, extending, and integrating these legacy systems are multiplying – rising licence costs, diminishing talent pools, platform constraints, and limits on innovation.
With Metatech Migration Works from TXP, organisations can move beyond the constraints of Gen to modern, supportable architectures, all with strong risk control, cost certainty, and functional equivalence guaranteed.
Why Migrate Off Gen?
| Challenge | Impact | Your Path Forward |
|---|---|---|
| Escalating licence/support costs | Growing operational burden | Replace proprietary dependencies with open, maintainable code |
| Shrinking Gen expertise | Increased delivery risk and reliance on expensive contractors | Transition to modern, widely available development skills |
| Legacy platforms | Limited scalability, integration, and agility | Adopt architectures that support cloud, APIs, and automation |
| Business pressure for change | Inability to respond to new demands | Free your team to focus on innovation, not upkeep |
How Metatech Migration Works from TXP Delivers
At the core of our Gen modernisation approach is our unique toolset, Metatech Migration Works from TXP, a proven, automated conversion engine originally developed by Metatech and now part of TXP. By combining this toolset with our deep delivery expertise, we help organisations migrate Gen systems to target architectures with confidence. Empower teams with knowledge transfer and upskilling to reduce reliance on external support.
Here’s how the process works:
Discover
Extract Gen application metadata to enable analysis, scoping, and planning.
Prepare
Rationalise and validate Gen models, eliminating redundant or invalid elements for a clean conversion base.
Extract
Convert metadata into a structured XML format, ready for transformation.
Convert
Use tailored code generators to transform XML into native source code in your chosen stack: Cobol (mainframe or emulation), Java, .NET, Angular/Typescript, Windows GUI / WPF, and more.
Adapt
Apply customisation, standards alignment, and client-specific refinements for production-ready output.
Delivery
This structured pipeline supports phased, low-risk migration, avoiding disruptive “big bang” cutovers and aligning delivery with business priorities.
CA Gen Modernisation – Remediation, Migration & Re-architecture
TXP’s Gen Modernisation approach goes beyond simple replatforming, we help organisations re-engineer legacy systems into high-performing, cloud-aligned, API-enabled solutions built for digital growth. Our modernisation services enhance system resilience, improve user experience and integrate seamlessly with today’s enterprise ecosystems.
From refactoring monolithic applications into modular architectures to enabling DevOps, automation and enhanced security standards, we transform complex legacy estates into flexible, innovation-ready platforms. The result is improved operational efficiency, reduced technical debt and a scalable digital foundation that supports long-term business transformation and competitive advantage.
Benefits of Metatech Migration Works from TXP
Functional Equivalence Guaranteed
Applications retain the same business logic and behaviour, without dependence on proprietary runtimes or licences.
Reduced Risk Through Incremental Delivery
Our methodology supports pilot migrations, test-first validation, and staged rollouts, protecting core operations.
Target Platform Flexibility
Migrate to mainframe (Cobol, CICS) or distributed stacks (Java, .NET, modern front-ends) depending on your roadmap.
Cost Certainty & Licence Elimination
Transition away from recurring Gen licence fees to a one-time conversion plus standard support costs.
Future-Ready Architecture
Unlock the benefits of cloud, APIs, business intelligence, and modern integration frameworks.
Skills Transfer & Sustainability
TXP provides knowledge transfer and capability building so your teams can thrive in the modernised environment.
CA Gen Conversion – COBOL, Java & .Net Code Conversion
At TXP, our Generation Modernisation services help organisations unlock the value of legacy platforms through structured, low-risk system conversion. We specialise in migrating ageing core applications to modern, secure and scalable architectures without disrupting business-critical operations.
Whether you are moving from legacy mainframe environments, upgrading outdated programming languages, or transitioning to cloud-ready infrastructure, our proven conversion frameworks ensure data integrity, performance optimisation and long-term maintainability. By combining deep technical expertise with rigorous testing, automation and governance, we reduce operational risk while accelerating time to value, enabling your organisation to lower costs, improve agility and future-proof core systems.

FAQs
Metatech Migration Works from TXP is a proven toolset and methodology for migrating Gen (formerly CA Gen) applications to modern, native architectures. It combines automated conversion with expert delivery to reduce risk, cut costs, and maintain functional equivalence.
Many organisations face rising licence costs, shrinking Gen expertise, and platform limitations. Migrating off Gen reduces dependency on proprietary systems, enables cloud and modern integrations, and ensures applications remain maintainable for the future.
Our toolset supports multiple target platforms, including mainframe Cobol (and emulation), Java, .NET, Angular/Typescript, Windows GUI/WPF, and other modern stacks, allowing organisations to align migration with strategic IT roadmaps.
Our structured, phased approach (Discover → Prepare → Extract → Convert → Adapt) combines automated conversion with rigorous validation and staged rollout, ensuring that business-critical applications remain fully operational throughout the migration.
Yes. The platform has been proven across large-scale, enterprise-level Gen portfolios worldwide. TXP’s experts tailor each migration plan to the client’s portfolio, risk profile, and operational needs.
Benefits include: functional equivalence of migrated applications, elimination of Gen licence costs, platform flexibility, incremental migration to reduce risk, modernised architecture, and knowledge transfer for internal teams.
Migration timelines vary depending on application size, complexity, and target platform. TXP works with clients to define a phased roadmap, ensuring predictable delivery and minimal business disruption.
Organisations can start by contacting TXP’s Gen Modernisation team. We perform discovery and assessment, define a migration strategy, and execute conversion and handover, providing a seamless transition from legacy Gen systems to modern architecture.
