Cloud migration often preserves rather than eliminates legacy when structural redesign is deferred. Re-legacy occurs when outdated domain boundaries, embedded behavioural coupling, and implicit integrations are rehosted under modern infrastructure abstractions. This compounds structural debt, financialises complexity, and stabilises fragility under the banner of transformation. True modernisation requires deliberate structural intervention (redefining boundaries, clarifying state ownership, and reducing coupling) not merely upgrading the substrate.
