Legacy Architecture Migration Patterns with DDD

" summary

Shows concrete migration choices at PayFit: splits employee data across three legacy systems, migrates some features by moving writes first and others by publishing translated events, and spends 1.5 years stabilizing those events while wrestling with model mismatches and null-string quirks. Compares CDC vs events and outbox/batch syncs, and reports AI helps more with project orchestration than code — a git-backed markdown + YAML tool plus Claude/Anthropic and Datadog cuts current-state mapping from weeks to ~30 minutes.
