Value propositions

The only legacy modernization that adapts to your software, migrates 100% of the code, and guarantees verifiable results.

Not all modernization technologies work the same way. While other solutions require adapting the system to the tool or manually completing part of the project, our technology is designed to preserve business knowledge and automate the transformation from start to finish.

Full adaptation to your architecture

Every organization builds on its own architectures, libraries, and standards. Our technology is customized to understand them and generate applications that integrate naturally, without imposing predefined architectures or creating dependencies on our platform.

100% automatic migration

We don't automate just part of the process: we transform the entire application while preserving business logic, data structures, and functional behavior. A complete modernization that eliminates manual development and reduces project risk.

A deterministic, traceable process

Modernization can't depend on interpretation. Every transformation is carried out through formal rules that always produce the same result for the same code, and every element retains full traceability back to the original system: auditable and verifiable.

Automatic test generation

Validation is one of the biggest costs in any project. We automatically generate test cases that verify the behavior of the modernized application and speed up validation, reducing manual effort and increasing confidence before going into production.

Technology designed to eliminate risk

Customization, full automation, deterministic processes, and automatic test generation combine to approach modernization with a level of predictability that's hard to achieve through traditional methods. Less uncertainty, less manual intervention, and a safe transition to the new platform.
Why we can say this
  • The transformation is deterministic, not generative.
  • There is full traceability between source and destination.
  • Customization is built on the client's own technology, not a standard architecture.
  • Validation is automated through test generation.

Our modernization services

From eliminating systems that no longer have support to giving you better development tools: we accompany you through every phase to transform your legacy systems without slowing down the business.

Elimination of unsupported systems

Applications built on technologies subject to end-of-life policies.

Objective:
  • Eliminate risks from unsupported applications
  • Eliminate technological obsolescence

Migration to new architectures

Maintain the same business functions on lower-cost platforms.

Benefits:
  • Licensing cost savings
  • Eliminate specialization requirements
  • Simpler platforms

Downsizing/Rehosting of applications

Preserve business processes while migrating to a new platform.

Benefits:
  • Reduced platform costs
  • Greater platform flexibility and agility
  • Modernization/Evolution

Better development tools

Critical systems that, after years of modifications, require an analysis to improve their maintainability.

Objective:
  • Technical-functional analysis
  • Dead code identification and removal
  • Rewrite estimation (migration/modernization)

OUR PROCESS

Step-by-step strategy

From analysis to production, in 4 phases
1

Analysis

We meet to understand the current environment.We assess the legacy system's language and architecture, identify technical challenges, and define the project scope.

2

POC

A small-scale proof of concept to demonstrate the feasibility of the migration. During this phase, the client can see the real benefits and results of the process firsthand.

3

Pilot

The next step is the pilot phase, where the old and new systems coexist. This stage is key to fine-tuning details and ensuring a smooth, uninterrupted transition.

4

Project

Once the pilot results are validated, the full project is executed. After a period of testing and evaluation, the definitive migration to the new environment takes place.

We understand your fears, and that's what makes us different from the rest

We know migration projects are scary, and we know why: broken promises, broken systems, last-minute surprises. That's why at GO4IT Solutions we don't offer just another "modernization." Our deterministic AI, based on formal grammars, guarantees exact, verifiable migrations with no business disruption. Our clients confirm it at the end of every project with us. We're different.

We ensure a successful migration

The technology we've developed over more than 10 years does deliver 100% automated translation.

We meet estimated timelines and costs

Thanks to our technology we are able to meet deadlines while keeping costs 60-80% lower than other alternatives.

Uninterrupted migration

Our phased methodology avoids disruptions to normal business activity, since each phase has its own defined purpose.

Seamless integration and adaptation

We adapt to our clients' own architectures, every modernization process is tailored to the environment.

Clear returns on investment and paybacks

We commit to finishing projects on time and without cost overruns. We have the technology, and we stand behind it.

Readable, maintainable code

Our clients certify the quality of the code in the early stages of the process. And so far, every one of them has confirmed it.

Vendor-independent

We don't lock you into a specific target architecture, and we leave no dependencies behind once the modernization process is complete.

You can trust us

Our technology was born at a technology research center and is the result of several research projects. And now, we've spent more than 10 years as a company offering modernization services with that same technology — which we continue to develop, adding new features and languages along the way. It's a battle-tested technology that ensures automatic migration/conversion from legacy systems to more modern ones, achieving project costs far lower than other modernization strategies.
