Why Modernize Legacy IT Systems?

01

Higher Security:

by closing vulnerabilities before they become headlines.

02

Lower Maintenance & Development Costs:

by moving to a comprehensive architecture that runs faster and can be easily extended, decreasing costs of future upgrades.

03

Increased Operation Stability:

by replacing unsupported, brittle components with continuously maintained ones.

04

Better User Experience:

by delivering faster load times, modern interfaces, and the flexibility to ship what customers expect.

05

Independence From a Single Developer:

by leaving you with documented, standards-based code that any qualified team can pick up — not locked to one person or vendor.

Global Stats

21–40%

of enterprise IT spending is tied up in technical debt from legacy systems.

22% / 48%

Only 22% of surveyed federal agencies say a majority of their IT systems are fully modernized, and 48% say legacy IT is a barrier to scaling AI.

Why AI Makes Modernization Affordable Now

Automated code analysis

AI maps legacy code, dependencies, and risk areas faster, saving the valuable work hours of our specialists.

Faster documentation

AI generates a comprehensive technical documentation for your old system and its upgrades.ģenerē visaptverošu tehnisko dokumentāciju vecajai sistēmai un tās uzlabojumiem.

Cheaper upgrading and migration

Partially automated code rewriting and test generation cut both effort and costs of upgrades, safety tests and system migration.

Smarter test automation

AI helps add test coverage to code that never had any, so changes can be made without breaking what already works.

Real-World Example: Reducing Infrastructure Costs

Captomatic had a 10+ years old system running on Ruby on Rails that needed to be modernized. With the help of AI, we transferred the system to Rust and optimized its architecture.

Legacy IT System Modernization Process

01

Technical and Security Audit

Assessing the architecture, technology and dependencies, security, observability, maintainability, performance and stability. Executive summary in business terms, spelling out the hidden costs of doing nothing.drošiem turpmākajiem biznesa lēmumiem.

02

Modernization Plan

Assessment of necessary fixes as a list of steps, priorities, urgency, costs and benefits.

03

First Modernization Stage

We execute the highest-impact step first to demonstrate tangible benefits, and hand you a system that's measurably safer, cheaper to run, and ready for next upgrades.

04

Planned step-by-step modernization

The next modernization steps happen at a mutually agreed pace. The system remains fully functional and independent from our support.

Frequently Asked Questions

What is IT system modernization?

IT system modernization means upgrading an outdated software system – its code, architecture, infrastructure, or all three – so it's more secure, cheaper to run, and able to support new features, without starting from scratch.

How much does system modernization cost?

The first modernization stage usually starts from €5 000. Exact scope and cost depend on the complexity and current state of your existing system. Exact cost can be calculated after audit results.

How long does modernization take?

Most projects run in phases rather than one long rebuild: a technical audit (weeks), a modernization plan (weeks), then a first modernization stage that delivers a measurable improvement before the next phase starts.

Can Legacy Systems Be Modernized Without Business Downtime?

Yes, due to a phased approach – start small, prove the approach, then expand. While individual parts are upgraded, the system as a whole keeps running.

Do we have to replace the whole system at once?

No! Modernization can mean anything from updating a framework version to fully decomposing a monolith into microservices. Most clients start with the highest-impact, lowest-risk scenario and expand from there.

How does AI make modernization cheaper and faster?

AI can map legacy code and dependencies in days instead of weeks, generate comprehensive documentation, add test coverage, and partially automate the migration itself – cutting both the cost and the risk of getting started.

What Are the Risks of Postponing System Modernization?

Outdated, unsupported systems become more expensive to run every year and are a growing security target – as the 2026 ransomware breach at “Latvijas valsts meži” shows, a single unpatched vulnerability can be enough for attackers to get in.

Is Using AI for Code Modernization Secure for Sensitive Data?

Yes! Where your data or business logic is sensitive, we run local AI LLMs instead of cloud-based models. You get the speed and cost benefits of AI-assisted modernization without exposing proprietary code or data to third-party services.

Can You Modernize a System Built by Another Developer?

Yes! If you have access to the source code, we can help you analyze the existing project architecture and define the necessary steps for modernization. Following the update, we also offer ongoing system maintenance and development services.
