  3. Deliverables and handover

With our Microsoft Solutions Partner designation and App Modernization on Microsoft Azure specialization, we modernize legacy applications while preserving working business processes and your team's domain knowledge. Each stage has clear acceptance criteria and a rollback plan, whether the target is Azure (AKS, Container Apps, App Service), multi-cloud or on-premises Kubernetes.

From discovery to handover

  1. Discovery and dependency map

    We analyze the codebase, external integrations and risks to establish the migration sequence.

  2. Characterization tests

    We record current behavior in automated tests so business rules do not change silently during migration.

  3. Target architecture and phased cutover

    We shift traffic gradually using strangler fig and feature flags, verifying each step with contract and parity tests.

  4. Handover

    We prepare runbooks and ship the final releases alongside your team to transition operational ownership.

Stacks we work with

  • ASP.NET WebForms and .NET Framework→.NET 10Minimal APIsBlazor
  • Java EE and older Spring versions (Spring 4 and before)→Spring Boot 3 and 4QuarkusHelidon
  • AngularJS and jQuery frontends→ReactNext.jsReact Router
  • On-premises monoliths→Service architecture on Kubernetes
  • Stored-procedure-heavy data layers→Application codeEvent-driven models

Deliverables and handover

  • Characterization and parity test suite verifying preserved behavior
  • Repeatable CI/CD and deployment pipeline
  • Observability dashboards and alert definitions
  • Runbooks and hands-on handover on the new stack
