Common questions about legacy application modernization diagram
Use strangler fig pattern wrapping legacy with new code, API facades exposing legacy as services, and incremental feature migration. Avoid complete rewrites - they usually fail.
Yes! Build modern React/Vue frontend consuming legacy backend via APIs. This gives immediate UX improvements while planning backend modernization. Show anti-corruption layer translating between old/new.
Identify bounded contexts, extract to services with clear APIs, use event-driven integration to decouple. Show how to maintain both systems during transition with feature flags.
Use views and stored procedures as abstraction, gradually introduce ORM layer, split database when services are stable. Visualize read/write patterns and data ownership migration.
Document as you modernize, capture business rules in tests, involve domain experts, refactor gradually while maintaining behavior. Show knowledge transfer from code to documentation.
