Execution Guide

Legacy .NET modernization playbook.

Modernize in controlled phases so your team can keep shipping features while reducing platform risk.

Phase-based modernization

Phase 1: Baseline performance, defects, and deployment risk
Phase 2: Isolate high-risk components behind stable interfaces
Phase 3: Modernize incrementally with automated regression checks
Phase 4: Standardize CI/CD and observability for long-term reliability

What to avoid

Large-bang rewrites with no incremental value delivery
Modernization plans disconnected from roadmap priorities
No owner for post-migration maintenance standards
