Oracle, SAP, legacy billing — your enterprise infrastructure runs on systems built 15 years ago. We modernize legacy systems without breaking what works: no big bang migrations, no theoretical roadmaps, just hands-on engineering from a team that has spent two decades building and maintaining mission-critical platforms processing hundreds of millions of euros monthly.
In tech, true autonomy strengthens bonds. By transferring knowledge and best practices, we enable independence while forging long-term partnerships, earning the trust of Europe's premier organizations.
Most modernization projects fail because the team underestimates what's inside the box. Legacy systems in production for 10-15 years carry undocumented business logic, custom workarounds, and integration points nobody remembers writing.
Legacy modernization fails when teams treat it as a greenfield project. It's not. The constraints are real: business logic buried in stored procedures, integrations nobody documented, and operations that can't pause while you rebuild.
Structured licensing audits that map real Oracle usage against entitlements. We identify consolidation opportunities, unused licenses, and optimization paths that reduce annual costs — often by six figures or more.
We've recovered over €1M for a single client and typically find 20-40% savings potential in every audit we conduct.
Telecom and utility billing systems accumulate dangerous technical debt. We rebuild billing engines from the inside, migrating business logic module by module while keeping production live and revenue flowing.
We document every rule before migrating it, validate with parallel processing, and only cut over when the new system matches the old one transaction-for-transaction.
Middleware that connects SAP with modern APIs, AFAS, custom ERPs, and cloud services. We handle data synchronization, error recovery, format translation, and audit logging across your entire integration layer.
We've built integration layers that process millions of transactions daily with built-in retry logic and real-time monitoring.
Every migration stage includes explicit rollback procedures. We build and validate the new environment against real data while legacy stays live. Cutover happens only when every validation gate is passed.
Your team participates in every decision point — no surprises, no unilateral actions, no hoping for the best.
Legacy modernization carries real risk. These are the questions decision-makers ask us before signing.
Most firms that claim legacy expertise have read about these systems. DNA Solutions has built and maintained them in production — Oracle billing stacks processing €300M monthly, SAP integration layers, telecom charging engines.
We run parallel environments: the legacy system stays live while we build, validate, and performance-test the new platform against real data. Before any cutover, we run parallel processing where both systems handle identical transactions simultaneously.
Simple integrations and Oracle optimization projects run 2-4 months. Full billing platform migrations typically run 6-18 months in phased delivery. We don't quote timelines before we've seen the system.
Yes. AI capabilities like predictive analytics and anomaly detection are layered onto existing infrastructure via API layers and data pipelines, without modifying your source systems.
