Correct answer: Rehost (lift-and-shift to AWS), Repurchase (move to a SaaS or new product).
Why this is the answer
The question asks for strategies with the least amount of effort for an application that cannot run in cloud environments as-is. Rehost (lift-and-shift) involves moving an application to the cloud with minimal changes, often by migrating virtual machines. This is a low-effort approach, as it doesn't require significant re-architecture. While the CMS "cannot run in cloud environments as-is," rehosting implies making it runnable, perhaps through minor configuration adjustments or using compatible services, without a full rewrite. Repurchase (drop-and-shop) means moving to a different product, typically a SaaS offering. This is also a low-effort migration strategy because the company simply adopts a new, cloud-native solution, eliminating the need to migrate or adapt the old application. Replatform involves making some cloud-specific optimizations (e.g., changing databases) but is more effort than rehosting. Refactor (re-architect) is the highest effort strategy, requiring significant code changes. Retire means decommissioning, which doesn't move the application to the cloud.
