Mainframe Modernisation, Migration and Support
TXP provides end-to-end mainframe services for organisations that depend on legacy systems but can’t afford the risk, cost or disruption of getting modernisation wrong.
Not every mainframe estate needs the same answer. Some need modernisation to extend and future-proof what’s already there, some need migration off the platform entirely and others need reliable, ongoing support to keep critical systems running. Oour teams bring decades of specialist experience across all three, that includes CA Gen, our team holds some of the deepest Gen modernisation expertise in the market.
We combine proven mainframe solutions with the right people to deliver them: automated tooling that de-risks technical execution, and a team who help you build the business case, sequence the transformation, and upskill your teams along the way.
Our Mainframe Services
Mainframe Modernisation Services
We help organisations restructure and modernise mainframe and CA Gen application portfolios without the disruption of a full replacement. Our approach starts with an automated assessment of your “as is” estate, from there our consultants define the most cost-effective route to your target state, covering rearchitecting, functionality isolation, block-mode splitting, componentisation and integration into cloud-enabled environments.
Mainframe Migration Services
For organisations that have made the strategic decision to move away from CA Gen or other legacy runtimes, our automated migration services convert applications into native code, including COBOL, Java or.NET, with no ongoing dependency on legacy runtimes. Migrations are delivered safely and cost-effectively, with minimal disruption to business-as-usual.
Mainframe Support Services
Our second and third-line support keep critical systems running while your teams focuses on transformation. We work alongside client teams to maintain and improve Gen and mainframe portfolios, ensuring business continuity, ongoing assurance and ready access to the specialist skills that are increasingly hard to hire.
Mainframe Consulting Services
Our consultants bring decades of mainframe and CA Gen experience to structured assessments, risk and dependency mapping, and roadmap development, so your legacy technology decisions line up with your commercial and digital goals rather than running alongside them.
Mainframe Training
We provide training and mentoring to build in-house CA Gen and mainframe capability. Our training academies have proven effective at growing client teams’ skills, reducing reliance on scarce external expertise, and supporting long-term platform ownership.
CA Gen Services
CA Gen expertise is TXP’s deepest specialism. We understand the value these systems still deliver, and we offer the full range of paths: tooling to modernise and restructure Gen portfolios where they’re staying, and automated migration using the Gen models themselves as the source where they’re not.
Why Organisations Turn to Mainframe Modernisation
Growth blockers
Legacy systems hinder business-wide agility, eating up more than 70% of IT budgets just for maintenance (Gartner). Modernisation frees resources, delivering up to 35% faster time-to-market (IDC).
Complexity paralysis
60% of digital transformations stall due to complexity and unclear goals (Gartner). TXP’s tailored roadmaps simplify your modernisation journey, providing clarity and confident execution.
Fear of disruption
A fear of downtime delays nearly 70% of digital transformations. TXP ensures seamless, secure, zero-downtime transitions to protect operational continuity.
Innovation lag
Legacy management consumes vital resources, stalling innovation efforts. Transitioning to adaptive, AI-driven platforms redirects efforts towards innovation and responsiveness.
Mainframe Consulting
Our mainframe consulting services give organisations the expert guidance they need to make informed decisions about the future of their legacy systems and applications. Through structured assessments and strategic analysis, our consultants identify risks, dependencies and opportunities, defining a clear roadmap that aligns mainframe technology with your wider digital infrastructure and business goals.

FAQs
Mainframe modernisation involves upgrading, restructuring or integrating legacy mainframe systems so they work more efficiently with modern technologies, applications, digital channels and enterprise IT strategies.

There are a number of risks when modernising mainframe systems. These risks include data migration integrity, service disruption, compliance issues and skills gaps. But with careful planning, phased rollouts and expert support – businesses can mitigate and manage these risks, preserving business continuity while modernising at the same time.
Yes. Modernisation can lower long-term maintenance costs by integrating with cloud and other modern platforms, automating processes, improving performance, and reducing reliance on scarce legacy skills.
