We migrate ageing iSeries, AS400, and monolithic systems to modern cloud-native architecture, with zero downtime strategies that keep your operations running throughout the transition.
Approach
Zero Downtime
Outcome
Risk-Managed
Modernization projects fail when they underestimate the complexity of legacy systems. We don't.
Leadership wants to modernize but fears that touching the legacy system will break critical business operations with no recovery path.
Strangler fig migration pattern, we build the modern system in parallel, migrate workloads incrementally, and decommission legacy components only when the replacement is proven.
Years of business logic are buried in COBOL, RPG, or AS400 code with no documentation, making it impossible to know what to migrate and what to rebuild.
Deep legacy audit and code archaeology, we map every business rule, data flow, and integration dependency before writing a single line of modern code.
Your business depends on a system that only a shrinking pool of specialists can maintain, creating dangerous single points of failure as that talent retires.
Migration to open, modern stacks, TypeScript, Go, cloud-native infrastructure, with full documentation so any competent engineering team can own it going forward.
We use a parallel-run strategy, the legacy system stays live while we build and validate the modern replacement. Traffic is shifted incrementally until the legacy system is fully decommissioned.
Always incrementally unless a full rewrite is genuinely justified. We assess each module independently, some get refactored, some get rebuilt, and some get replaced with modern SaaS tooling.
Scope varies enormously. A focused module migration can take 8–12 weeks. A full enterprise platform modernization typically runs 6–18 months with phased delivery throughout.
Data integrity is our first priority. We run parallel data pipelines, validate every record against the source system, and never cut over until reconciliation is 100% confirmed.
