Legacy Modernisation — Auckland

Transform legacy systems into scalable, cloud-native platforms. Dealoptions helps NZ organisations modernise with minimal business disruption.

  • Platform re-architecture & microservices
  • Cloud migration & rehosting
  • Security hardening & compliance (NZ standards)
Legacy code modernization

Why modernise?

Reduce risk

Eliminate single points of failure and unsupported tech stacks.

Lower TCO

Move to cost-effective cloud services and maintenance patterns.

Faster delivery

Adopt CI/CD and agile teams to iterate quickly.

Our phased approach

We deliver modernization in predictable phases so operations keep running while value is unlocked incrementally.

  • Assessment & roadmap
  • Strangler pattern & component extraction
  • Replatform / refactor to microservices
  • Migrate data and stabilise
  • Operate & iterate

Services we provide

Assessment & Roadmap

Codebase health, dependency mapping, risk assessment and phased roadmap aligned to NZ business needs.

Re-architecture

Microservices design, API contracts, data migration patterns and scalable infra.

Cloud migration

Rehost, replatform, or refactor onto AWS/GCP/Azure with cost and compliance controls.

Auckland council legacy lift — Case study

We helped a mid-size public-sector org modernise a payments and records platform. Outcomes: 40% cost reduction, zero downtime migration window, and improved security posture.

  • 6-month assessment and pilot
  • Incremental strangler deployment
  • Automated CI/CD and infra-as-code
