Modernization Benefits

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

A Global Pattern

40%

of US firms still experience weekly IT glitches caused by legacy systems.

Deloitte, Tech Trends 2026

21–40%

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

KPMG, 2026 Annual US Technology Survey

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.

A Real Breach, Close to Home
In June 2026, the IT systems of Latvijas valsts meži (LVM), Latvia's state forestry company, were breached. As a response, Cyber Incident Response Institution of Latvia released a list of security issues that need to be addressed (Cert.lv). The majority of these issues are a part of legacy systems, waiting to be exploited.

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.

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.

A Case Study of Modernization
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. The tangible benefits included: 3x lower infrastructure costs, 2x faster video and photo delivery to clients and minimized supply chain attack risks.

How We Get There

01
Technical 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.
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?
It depends on what the audit finds. Every modernization starts with a technical audit that maps your system's risks and options, so you get an exact cost and scope before committing to a plan – not a guess.
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 we modernize without disrupting the business?
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 happens if we don't modernize?
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 it safe to use AI on our sensitive data and business logic during modernization?
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.
