Legacy Application Support
Modern solutions for legacy applications. TXP delivers robust, future-ready support and transformation for critical legacy enterprise applications. Our proven approach balances deep technical expertise with industry insight, helping businesses reduce risk, improve performance, and unlock innovation through modernising their legacy applications, without disrupting what already works.
By revitalising your existing systems and applications, TXP helps you meet today’s modern business demands. At TXP, we leverage over 20 years of experience and with our in-house expertise, we transform outdated legacy applications using modern architectures, advanced technologies, and cloud-native solutions – ensuring a smooth, secure, and cost-effective transition that unlocks long-term value for your organisation.
Legacy Application Modernisation
At TXP, we specialise in helping organisations modernise their legacy applications, with a strong track record across platforms such as .NET, Java, Angular, and React, and cloud ecosystems like Azure and AWS. Our approach balances technical modernisation with operational stability, data security, and long-term optimisation.
Modernising While Minimising Downtime
Legacy applications often support critical business processes that are the backbone of an organisation’s operations.
Rearchitecting for the Future
We address this by rearchitecting monoliths into microservices, enabling greater scalability and easier maintenance
Data Security & Compliance at the Core
We mitigate these by implementing role-based access controls in Dynamics 365 and Power Platform, aligning with modern security standards.
Post-Migration Optimisation
This includes performance tuning with tools like Application Insights on Azure to proactively monitor and optimise workloads.
Application Modernisation Services – for Legacy Applications
Legacy projects are rarely predictable. They’re often bespoke and complex. Legacy systems are often stitched together over time, and involve components that don’t talk to each other and integrate. TXP is built to handle this complexity. We work on:
– Disconnected, standalone products with no integration between systems
– Systems that generate siloed data and no single source of truth.
– Outdated platforms with no internal knowledge of how they work
– Long-deprecated software still critical to day-to-day operations
– Highly bespoke codebases with undocumented dependencies
Our approach is never one-size-fits-all. Instead, we deeply assess, validate, and design holistic solutions that fix not just what’s broken, but what’s holding your business back.
Benefits of Application Modernisation
New Features
Legacy systems often block the rollout of new business features and functionality. We refactor and modularise applications, making it easier to implement new APIs, features, frontend interfaces, or integrations with modern services.
Scalability
We migrate applications to cloud platforms like Microsoft Azure or Amazon Web Services (AWS), allowing systems to scale dynamically as your business grows based on usage, ensuring performance and cost-efficiency.
Efficiency
Our reengineering processes streamline codebases and remove technical debt from existing estates, improving load times, developer velocity, and the long-term maintainability of your applications.
Improved Performance
From frontend optimisation to backend service tuning, we improve application response times, stability, and uptime which enhances user satisfaction across different platforms.
Cloud Migration
We handle full-stack cloud migration, including database transitions, storage solutions, and networking setups, ensuring seamless service continuity across your organisation.
Microservice Setup
TXP helps break down legacy monoliths into manageable microservices, boosting fault tolerance, deployment speed, and team autonomy.
Security & Compliance
We enforce and deploy modern security best practices across all of our work, including encryption, RBAC, secure APIs, and audit logging. This helps organisations meet compliance benchmarks with confidence.
Easy Management
TXP builds maintainable architectures with modern DevOps practices, documentation, and automated monitoring, helping to reduce the burden on internal IT and technical teams.

FAQs
That’s common. TXP’s team includes senior architects and reverse engineering experts who specialise in understanding and rebuilding undocumented, bespoke systems.
Yes. We build data pipelines, lakes, and integration layers to consolidate data and eliminate silos.
Absolutely. We provide full documentation, training, and ongoing support. Our goal is to empower your teams, not create dependency.
If your system is slow, unsupported, difficult to update, or doesn’t integrate with modern services—it’s likely time to modernise.
This depends on the complexity of your systems. We begin with an assessment and roadmap, then deliver in phases using agile methodologies.
Support keeps an existing legacy system stable, secure, and running as it was intended. Modernisation changes the underlying technology behind your application architecture, or platform.
