Legacy Software Modernization

Unlock the potential of your legacy systems. We use AI to make modernization up to 87% faster and safer — without business disruption.

Why modernize?

The old system is actually a greater security risk than modernization. Outdated systems often lack modern security standards (OAuth, encryption), making them vulnerable.

Technical debt is the "interest" you pay for maintaining old and complex code. It manifests as slow development, frequent bugs and high maintenance costs. AI helps aggressively reduce this debt.

Our "Strangler Fig" method means you don't have to rewrite everything from scratch. We replace the old system piece by piece with new, modern microservices or agents, while keeping the old system running. This mitigates risks and ensures business continuity.

Why Choose Alder Solutions?

Up to 87% faster

AI tools analyze legacy code, map dependencies and automatically document business logic.

Safe process

Strangler Fig method — we replace the old system piece by piece, keeping the old system running.

Guaranteed results

Automated regression tests ensure that the new system produces identical results.

Reduced technical debt

AI rewrites code to meet modern standards, reducing future costs.

We combine deep engineering (at the code level) with a strategic perspective. We are not just "developers" — we are architects who use AI as a tool, not a crutch.

Our Process

01

Analysis and mapping

We use AI tools that analyze legacy code, map dependencies and document business logic. Initial audit ready in weeks.

02

Making data AI-ready

Old databases are often unreadable for AI. We clean, structure and create API layers so modern AI agents can access the data.

03

Incremental modernization

Strangler Fig method — we replace the old system piece by piece with new, modern microservices or agents. Business continues without interruption.

04

Testing and validation

AI generates tests based on the old system's behavior. Automated regression tests ensure the new system produces identical results.

05

Security standards and optimization

We implement modern security standards (OAuth, encryption) and optimize performance. The old system was the greater security risk.

Frequently Asked Questions

We have an old system (e.g. legacy .NET, Java) that nobody dares to touch. Can AI help?

Absolutely. This is one of our key strengths. We use AI tools that can analyze legacy code, map dependencies and document business logic that nobody remembers anymore. This makes modernization up to 87% faster and safer.

Does modernization mean rewriting everything from scratch?

No. We prefer the 'Strangler Fig' method — replacing the old system piece by piece with new, modern microservices or agents, while keeping the old system running. This mitigates risks and ensures business continuity.

Can I continue using the system during modernization?

Yes, our process is designed so that business operations are not interrupted. New modules take over work gradually.
