Migration & AI Modernization
Your aging foundations slow your business and weigh on your budget. At Wide x TALAN, we accelerate your migrations and version upgrades with AI, analysis of the existing setup, AI-assisted rewriting, automated testing, to cut delays, secure the run and clear technical debt, with no service disruption and no loss of compliance (FADP, local hosting).
End-of-life frameworks, unsupported versions, code no one masters anymore: technical debt slows your evolution, increases risk and drives up the bill. AI changes the game, it accelerates analysis, rewriting and testing, where manual migration was too slow and too risky.
Obsolete frameworks, languages and runtimes: security holes, incompatibilities and increasingly costly maintenance.
Old, poorly documented code whose authors have left: every change becomes slow and risky.
Migrating without interrupting production: the trajectory must be progressive, reversible and tested at every step.
FADP, security patches, audits: staying on supported versions is no longer an option but an obligation.
Manual migrations are long and expensive; AI reduces the effort on repetitive, low-value tasks.
Modern architectures, accessible APIs and data: the prerequisite for leveraging generative AI on your use cases.
AI accelerates migration, but it raises legitimate questions on the IT side. Here's how we answer them concretely, on every project.
Your data shouldn't transit through an uncontrolled US-based model? We choose the model (proprietary, open source or sovereign) and its hosting based on your constraints, never the other way around: Swiss or European cloud, on-premise or air-gapped if required.
Going twice as fast is worthless if it's less reliable. Every line migrated by AI goes through auto-generated regression tests and a human review before cutover: the speed gain never comes at the cost of quality.
AI shouldn't make your teams dependent or cause them to lose command of the code. We document every migration decision and transfer knowledge to your developers, so the modernized foundation stays understood and maintainable in-house.
From a costed assessment to a modernized application: we move forward in short stages, with a concrete deliverable at the end of each sprint.
Trajectory & costed roadmap
The scan that turns the unknown into a costed action plan.
Keep the existing code, rewrite on top of it, migrate elsewhere: the right path depends on your context, and it's an architect's call, not an algorithm's. We frame the trajectory with your teams, then measure the actual volume to handle (by IS, application, module or library) to produce a roadmap costed in person-days, complemented by a technical debt score and a vulnerability inventory (CVEs). We recommend starting with a pilot representative of every impact, to validate the trajectory before industrializing.
Learn moreAccelerated go-live
Modernizing in a few weeks what used to take months.
The assessment is done, time to modernize without rewriting everything blindly? Depending on your scenario, massive version upgrade (Angular 1→18, PHP 5→8), stack migration by transpilation, or security remediation (CVE, FADP), we combine auto-generated regression tests, human review and progressive rollout. You stay in control at every step, with no big bang and no service interruption.
Learn moreAI is not a fad: we use it concretely to understand the existing setup, accelerate rewriting and make testing reliable, under the control of our experts, at every step.
Mapping of legacy code, dependencies and business rules reconstructed automatically.
Code conversion, version upgrades and refactoring accelerated by AI, validated by our developers.
Generation of automated tests to secure each stage and guarantee service continuity.
Across both offerings, we remain agnostic about the AI model used, proprietary, open source or sovereign, in the cloud or on-premise. The choice adapts to the client's context: security, data sovereignty and compliance.
Each phase produces a deliverable, clears a decision gate and triggers the next one. You decide at every gate.
Install and validate the stack, the developer harness, CI and permissions before any analysis.
Deliverable : Versioned stack, operational harness, deterministic CI, confirmed access.
Make modernization decidable: identify every impact, measure their scale, propose a costed trajectory.
Deliverable : Impact matrix, low/likely/high cost estimate, trajectory sheet.
Prove the trajectory and the harness on a real scope, calibrate effort, verify the guardrails.
Deliverable : Transformed scope, recalibrated cost estimate, detailed plan, documented failures.
Make the method reproducible by any team, with no dependency on the initial expert.
Deliverable : Reusable package, trained teams, recalculable KPIs.
Not a vendor doing blind "lift and shift." A partner committed to the durability of the foundation.
AI tools and methods proven on real code, with humans keeping control.
Migration, cloud, security and integration expertise: your IT department is supported end to end.
FADP under control, local hosting, knowledge of regulatory and sector constraints.
Version upgrade, replatforming or rebuild: we choose the trajectory at the right cost.
