Why It Matters

Are you still chained to outdated systems? You’re not alone — and we understand.

Outdated technology burns your budget, slows growth, and blocks innovation. Every old line of code creates hidden debt. According to Gartner, nearly 70% of organizations say that outdated infrastructure is the biggest barrier to digital transformation, costing millions in hidden operational costs.

Our re-platforming solutions cut through the noise. With in-depth app analytics and business case analysis, we deliver change that makes a difference. Scalability? Built in from day one. So you’re not just catching up — you’re ready for the future.

When Does it Fit

When Does it Fit

01

Sluggish performance?

Your applications take forever to load, that drains productivity and patience.

02

Downtime again?

You’re tired of firefighting. Downtime impacts customer trust and drains engineering resources.

03

Security holes?

Your system simply doesn’t get along with modern tools, APIs or the cloud.

04

Integration is a nightmare?

Your systems can’t talk to modern tools or cloud platforms.

05

Maintenance instead of dynamism?

Legacy systems consume your budget with outdated licenses and scarce support talent.

06

Scaling is painful

You want to grow, but your architecture says no. Scaling means risking the whole stack.

07

Your stack scares off top talent

Legacy tech makes onboarding difficult and demotivates top talent.

What We Offer

Legacy Modernization Services We Provide

  • Enterprise App Modernization Consulting

    Legacy systems eat up budgets, slow innovation, and expose you to risk. Without a clear plan, teams get stuck in maintenance mode.

    We will provide you with a clear roadmap based on a comprehensive analysis of your applications, an evaluation of your technical debt, and a modernization strategy tailored to your business. Whether rehosting or a complete rebuild, we reduce risk and achieve greater flexibility.

  • Legacy Application Migration

    Migration is more than just moving code — it’s about freeing yourself from legacy constraints. We review your architecture, uncover hidden risks, and transform monolithic systems into clean, modular, API-driven platforms.

    From platform conversions to secure data migration, we modernize every layer — code, architecture, and infrastructure — without sacrificing the essentials.

    We help you move fast and be ready for the future.

  • Cloud Modernization

    We go beyond lift-and-shift to completely transform your applications for the cloud. Legacy systems are transformed into microservices, containerized for scale, and integrated with cloud-native tools like Lambda, Azure Functions, and App Engine.

    We fine-tune performance, remove bottlenecks, and automate everything from CI/CD pipelines to infrastructure as code. With built-in observability and compliance, your cloud runs faster, safer, and smarter.

  • Data Modernization

    Outdated data systems don’t just slow you down — they hold your business back. We modernize every layer of your data stack, from infrastructure to compliance, transforming legacy databases into agile, cloud-native platforms.

    We migrate systems like Oracle or DB2 to PostgreSQL, MongoDB, and more — with integrity, minimal downtime, and zero guesswork. Pipelines get a complete upgrade with automated ETL/ELT flows, while cloud-native architectures power scalable storage and computing.

  • AI/ML Implementation

    We use AI to refactor, document, and modernize legacy code quickly.

    With tools like GitHub Copilot and custom LLMs, we transform outdated code into clean, maintainable frameworks, extract hidden logic, and automatically generate documentation. ML models turn dormant data into business insights, while AI-powered tools detect errors and create test cases on the fly. Free your team from the drudgery.

  • UX/UI Modernization

    Outdated user interfaces hinder productivity and frustrate users. Using leading front-end frameworks like React, Vue, or Angular, we transform user interfaces into fast, intuitive, and visually modern experiences.

    From elegant SPAs and mobile-ready PWAs to accessible upgrades and performance enhancements, we deliver a smooth, compliant UX for today’s users. Great software deserves a great experience.

  • Code Refactoring

    We transform messy, outdated code into clean, maintainable, scalable systems — without compromising your core logic.

    By reducing technical debt, optimizing legacy code, and increasing performance, we make your applications faster, more stable, and easier to develop.

    We modernize outdated stacks and integrate test automation and CI/CD to ensure smooth and fast releases.

  • API Extension

    Disconnected legacy systems slow everything down. We create secure, scalable REST APIs that connect your legacy applications to modern platforms without you having to rebuild them from scratch.

    From API wrapping to SaaS integration and event-driven architecture, we transform rigid systems into agile ecosystems. With integrated security and scalable infrastructure, your data flows quickly, securely, and exactly where needed.

Our Approach

Our Modernization Strategy

Our process is deliberate, data-driven and designed to uncover risks, eliminate bottlenecks and create the foundation for continued growth.

01.

01. Step 1

We start by dissecting your legacy stack with surgical precision — peeling back every layer to understand where your technology is supporting growth and where it's silently undermining it.

02.

02. Step 2

We define modernization goals that are truly business-viable. We isolate the critical systems, uncover the dependencies, and expose the hidden technical debt.

03.

03. Step 3

We re-design the architecture for longevity, not just compatibility. Every decision is based on your strategy: cloud-native, composable, and scalable.

04.

04. Step 4

We systematically decouple legacy components and plan every step of the transition. No hasty migrations. Just a deliberate, data-driven transition to a cloud-native infrastructure.

05.

05. Step 5

We deliver a roadmap: step-by-step execution, allocated resources and clear risk buffers. Modernization becomes measurable, manageable and meaningful.

Value We Provide

Why Should You Work With Us on Legacy Modernization?

01

Built for the Future

We design and execute large-scale migrations with precision, moving enterprise systems from brittle, legacy infrastructures to robust cloud-native ecosystems on AWS, Azure, and GCP. Our methodology consistently reduces infrastructure costs by up to 35% while increasing fault tolerance, resiliency, and performance across the board.

02

Easy-to-Maintain Tech Stacks

We develop clean, modular systems based on .NET 8, built on gRPC, REST APIs and SignalR, designed for customizability and easy evolution. This modernization eliminates technical debt at the root and enables teams to accelerate release cycles by up to 50% through fully integrated CI/CD pipelines.

03

Advanced DevOps

We embed automation and orchestration directly into the development lifecycle. Kubernetes, Infrastructure as Code, AWS Lambda, Azure Functions — these are not tools that we will add later but fundamental elements of our deployment model. Intelligent pipelines take over the provisioning, testing, and deployment of environments and reduce rollout times by more than 70%. Teams gain efficiency without compromising stability or security.

FAQ

Frequently Asked Questions

  • Why modernize when our legacy systems are still in operation?

    Over time, legacy systems accumulate technical debt, create security blind spots and limit your ability to evolve. Modernization is a proactive decision. It reduces long-term risk, strengthens performance and positions your infrastructure to support innovation, not stifle it.

  • When will we see the first results of modernization?

    The first results are quick — within 3 to 6 months, companies typically report lower infrastructure costs and faster performance. The full return on investment is achieved within 12 to 18 months. From then on, the value continues to increase, both operationally and financially.

  • Are the upfront costs of cloud migration really worth it?

    Yes. Moving to the cloud reduces infrastructure costs by up to 35%, eliminates the need for hardware maintenance and scales with demand. You avoid overprovisioning and achieve long-term savings that far exceed the initial costs.

  • How do you avoid disruption during migration?

    We use a phased, precision-tested approach. Legacy systems remain active during the changeover, and constant monitoring allows us to resolve issues before they arise in production. No risk from a big bang. Just a deliberate, seamless transition.

  • How is our data protected during the migration?

    Data integrity is maintained at every step. We combine automated safeguards with human oversight, real-time monitoring and post-migration validation. Redundant backups and strict security protocols are built into the process from start to finish.

  • Do we stay compliant during modernization?

    Yes. We design every phase with compliance in mind — ISO 27001, GDPR, HIPAA and industry-specific requirements. Compliance is not retrofitted. It’s already built in.

  • Why choose Devox software for modernization?

    Because Devox doesn’t just do migrations — we lead the transformation. From cloud architecture to full implementation, we bring deep expertise, a consultative approach and a relentless focus on business outcomes. Our track record: measurable gains, minimal disruption and complete transparency.
