Code is reworked to use cloud APIs and eventing while preserving external behavior for the grants portal. Which migration strategy is this?
Select an answer to reveal the explanation.
Short Explanation
Refactor is rewriting the engine so it uses cloud APIs and events, but the car still drives the same routes for citizens. External behavior stays; internals get cloud-smart. That is deeper than lift-and-shift and different from shutting the app down.
Full Explanation
Refactoring alters application code to integrate cloud APIs, messaging, or similar services while aiming to preserve external behavior. It improves cloud fit without necessarily the full structural redesign implied by re-architect. Rehost avoids code change; retire and retain do not modernize the grants portal toward cloud services.
