Migration Journey Example Set

This set focuses on one of the most common enterprise scenarios: migrating the integration layer from BizTalk Server to Azure Integration Services while core business systems remain unchanged. It builds on the BizTalk example set (current state) and the Azure Integration Services example set (future state).

The pages explain migration patterns, coexistence, and capability mapping as a mini case study with phased migration logic, not a big-bang replacement. Each page holds ready-to-import C4 Diagrams markup in Mermaid that you can import into a C4 Diagram Set in Nodinite.

What You Learn

  • ✅ How to represent current state and future state in one architecture narrative.
  • ✅ How to model phased coexistence during migration.
  • ✅ How to map legacy BizTalk capabilities to Azure-native equivalents.
  • ✅ How to model coexistence safely while preserving core business platforms.

Diagrams in This Set

Diagram Purpose
L1 Context Diagram Example Show the integration-layer transition while Portal, ERP, ERP-Finance, and Warehouse Management System stay unchanged (context diagram).
L2 Container Diagram Example Show real-world coexistence with shared systems and split workloads (container diagram).
L3 Component Diagram Example Show old-to-new capability mapping at implementation level (component diagram).

Read the pages in order (L1 → L2 → L3) to follow the C4 zoom hierarchy from the migration journey context down to the capability mapping.
