Modernize Without the Headache
Legacy systems can silently kill growth. They’re slow, expensive, and hard to scale. At TwinCore, we help companies ditch outdated tech stacks, eliminate security risks, and transform their software with minimal downtime.
From UI/UX updates to deep code refactoring - we do it all.
Our Software Modernization Services
Database Modernization
Outdated databases slow down applications and limit data flexibility. We help modernize MS SQL, PostgreSQL, and MongoDB schemas and performance - enabling faster queries, lower latency, and cloud-native scalability.
CMS Modernization
We migrate content-heavy platforms from outdated CMS systems to modern ones with responsive design, SEO optimization, and easy content workflows.
Framework Modernization
We upgrade apps built on outdated or deprecated frameworks to modern stacks like .NET Core, Angular 17, and React 18 - improving maintainability, performance, and developer experience.
Cloud Modernization
Legacy systems stuck on-prem or running on old IaaS models? We refactor applications to cloud-native architecture on AWS, Azure, or Google Cloud - using containers, managed services, and autoscaling.
Code Modernization
We clean up legacy codebases, apply SOLID principles, decouple business logic, and eliminate tech debt - making your code lean, testable, and extensible.
Architecture Modernization
Monoliths become bottlenecks. We refactor to microservices or modular architecture, enabling faster deployments, easier scaling, and improved fault tolerance.
UI/UX Modernization
We redesign outdated interfaces to match modern expectations: mobile-first design, improved accessibility, better navigation, and faster page loads - all built with React or Angular.
Why Modernize Legacy Software?
Security Risks
Legacy software often relies on outdated frameworks with no longer supported security patches - making them vulnerable to cyberattacks and data breaches.
High Maintenance Costs
Old systems require constant bug-fixing and manual workarounds. Modernized apps cut maintenance costs, allowing teams to focus on new features, not firefighting.
Infrastructure Waste
Legacy apps overuse CPU/RAM, leading to high hosting costs. With modernization, you’ll reduce overhead by moving to efficient cloud environments.
Poor Performance & Scalability
Legacy systems struggle under high loads. Modernized software can handle real-time traffic spikes, concurrent users, and grow with your business.
Outdated UX
Modern users expect fast, clean, responsive interfaces. Legacy UIs feel clunky and can’t compete - especially on mobile.
Limited Integration
Old systems can’t easily connect to modern APIs, analytics tools, CRMs, or automation platforms. We fix that.
Frameworks We Upgrade & Modernize
.NET Modernization
We migrate from .NET Framework to .NET 6+ / .NET 8, enabling cross-platform performance, better memory handling, and modern DevOps pipelines.
Angular Modernization
Upgrade from AngularJS or legacy versions to the latest Angular - improving performance, maintainability, and long-term support.
React Modernization
We modernize React apps to support latest best practices, TypeScript, Redux Toolkit, Server Components, and performance optimization.
Database Modernization Expertise
MS SQL Modernization
optimized schemas, indexing, query performance
PostgreSQL Modernization
relational power with open-source flexibility
MongoDB Modernization
schema validation, aggregation tuning, and scaling
Cloud Modernization Platforms
AWS Modernization
EC2 to ECS/EKS, RDS, Lambda
Azure App Modernization
Azure Functions, App Services, CosmosDB
Google Cloud Modernization
Cloud Run, Firebase, GKE

How We Approach Software Modernization at TwinCore
Our approach to modernization starts with a full audit of your current software. We analyze the architecture, codebase, performance, and integration landscape to understand how your system works and where it fails to meet modern standards. This includes assessing code quality, outdated dependencies, UI and UX bottlenecks, and security risks. Based on this audit, we build a step-by-step strategy that aligns with your business goals and minimizes risks. We don’t offer one-size-fits-all solutions - we tailor modernization plans to your existing infrastructure, team capacity, and future scaling needs.
Throughout the project, we provide full transparency: weekly updates, clear milestones, and deliverables you can track. Our goal is not just to update your system, but to make sure it becomes faster, more reliable, and easier to scale as your business grows.
Minimal Downtime, Zero Disruption
One of the most common fears about modernization is breaking what already works. At TwinCore, we eliminate that fear through careful planning and a parallel implementation strategy. We run modernization in isolated environments, test thoroughly, and deploy in stages to avoid any impact on your live system. Data integrity, uptime, and user experience remain fully protected throughout the process. We also prepare rollback procedures and include pre-launch validation to ensure the new system is not just compatible but significantly better. With us, modernization doesn’t mean downtime - it means forward motion.
We Modernize the Systems Others Won’t Touch
Over the years, we’ve worked with software that hadn’t been touched in over a decade. Many of our clients come to us with systems built on obsolete technologies, undocumented codebases, or infrastructure that no longer scales. We don’t shy away from that. Our team is used to diving deep into complex monoliths, unstable APIs, and old frameworks, then rebuilding them with clean, modular, cloud-optimized architectures. If your current system feels like a ticking time bomb - we’ll turn it into a solid foundation for growth.
Why Choose TwinCore?
Modernization isn't just about rewriting code - it's about giving your software a second life. At TwinCore, we revitalize legacy systems into modern, scalable, cloud-ready solutions that perform faster, cost less to maintain, and are easier to evolve.
We bring deep expertise in .NET, Angular, React, and cloud platforms like AWS and Azure. Whether you need a full architectural overhaul or a focused modernization of your codebase, we deliver future-proof, high-performance systems - without disrupting your business.

FAQ
What is software modernization, and why does it matter?
Software modernization is the process of updating outdated systems to modern platforms, frameworks, and architectures. It’s crucial for improving performance, reducing maintenance costs, eliminating security risks, and enabling your business to scale. Without modernization, legacy software becomes a barrier to innovation and growth.
How do I know if my software needs modernization?
If your system is slow, difficult to maintain, incompatible with modern tools, or reliant on outdated technologies - it’s time to modernize. Frequent bugs, high infrastructure costs, and poor UX are all red flags. We can audit your system and give you a clear modernization roadmap.
Will I lose any data or functionality during modernization?
No. Our process ensures 100% data preservation and seamless transition. We carefully map all business logic and migrate your system in stages, ensuring that no data or features are lost - and that everything works better than before. We prioritize stability and accuracy at every step.
How long does a typical modernization project take?
Most modernization projects take between 1–4 months, depending on the size, complexity, and technologies involved. We provide a detailed estimate after auditing your system, and we work in agile sprints to keep you updated and involved throughout the process.
Can you modernize both frontend and backend?
Absolutely. We specialize in full-stack modernization - from upgrading the frontend with React or Angular, to rebuilding the backend in .NET Core or Node.js, and optimizing database and cloud architecture. Whether it’s a full rewrite or modular upgrades, we handle it end-to-end.
What makes TwinCore different from other providers?
We don’t just rewrite code - we rebuild your software with a business-first mindset. Our team combines deep technical expertise with practical understanding of real-world scalability, UX, and security. With TwinCore, you get a reliable, forward-thinking partner, not just a dev shop.
