Information System Modernization
Information System Modernization
Your systems carry your critical operations, but they slow your teams down. We modernize without disruption, brick by brick, with a trajectory you control.
The challenge
Why modernizing is so difficult
Technical debt accumulates
Every workaround today becomes tomorrow's risk. Cycles lengthen, changes become frightening.
Change is frightening
The older the code, the higher the perceived risk. Every decision is deferred to avoid breaking everything.
Knowledge evaporates
The people who know the system leave. Documentation hasn't kept up. Opacity becomes structural.
Our 3 invariable principles
No big bang
Successive incremental evolutions. Service continuity is a constraint, not a secondary objective.
No tunnel
Frequent deliveries, continuous feedback. You see progress at every step.
No blind spots
Impact analysis before every change. Documentation kept up to date throughout the project.
Typical trajectory
A progression in 4 steps
01
Audit & mapping
Identify technical debt and real risks. A prioritized, actionable plan within 2 weeks.
02
Trajectory
Preserve what works, isolate critical components, prioritize by business value and quick ROI.
03
Progressive execution
Targeted refactoring, APIsation, Cloud migration. In secured, tested, documented steps. No tunnel.
04
Sustainment
The system transitions into our MCC so technical debt never re-accumulates.
Modernization without service disruption
From opaque architecture to progressive mastery, step by step, no big bang.
- Coupled monolith Quarterly releases, impossible rollback, paralyzed teams.
- Orphaned code No documentation, turnover = major risk.
- Very long cycles 6 to 12 months between each major evolution.
- Fragile dependencies Every change can break something elsewhere.
- Modular architecture Strangler Pattern, tier-by-tier migration, no interruption.
- Living documentation AI used to re-document and map existing code.
- Continuous CI/CD Daily deploys, automated tests, 1-click rollback.
- Full observability Structured logs, metrics, real-time distributed traces.
Method
Two invariants of our approach
Strangler Pattern
We wrap the old system, isolate critical components and replace brick by brick.
Software archaeology
COBOL, legacy Java, forgotten PHP: we use AI to re-document orphaned code, extract buried business rules and identify real blind spots. What once took months of deciphering is reduced to a few days of analysis.
What you gain
Technical debt reduction
Readable architecture, maintainable code, teams that move forward with confidence.
Business continuity
No disruption imposed on your teams or your clients during the migration.
Faster delivery cycles
Frequent releases, short feedback loops, shared progress.
Long-term trajectory
A modernization aligned with your operational constraints over time.
Frequently asked questions
-
By applying the strangler pattern: wrapping the old system, isolating critical components and replacing them brick by brick, with no big bang. Service continuity is a design constraint, not a secondary goal.
-
A progressive modernisation technique that lets old and new systems coexist, gradually routing traffic to new components and retiring the old one only once the new one is validated in production.
-
Through AI-assisted software archaeology: source code is analysed to extract buried business rules, identify true blind spots and rebuild usable documentation,what normally takes months of deciphering is reduced to a few days of analysis.
-
No. A complete rewrite (big bang) is the riskiest scenario. We favour successive evolutions with regular production releases, short feedback loops and technical debt that decreases with each iteration rather than rebuilding.
