A client is migrating the content from a legacy website to an existing AEM implementation. An Architect evaluates the content of the legacy site and…

The most efficient and fastest approach for this scenario is a hybrid strategy. The large volume of structured content (20,000 pages) is ideal for automation using an ETL (Extract, Transform, Load) process. This leverages scripts to migrate content quickly and consistently. For the few hundred unstructured pages, the effort to create custom migration scripts would outweigh the benefits. Manual authoring for these exceptions is more time- and cost-effective. This combined approach directly addresses the client's need to complete the migration as soon as possible by applying the best method for each content type.

A. This option is incomplete as it fails to address the migration strategy for the few hundred unstructured pages.
C. The Site Importer is for simple sites and imports rendered HTML. It does not create structured, editable AEM components, which is required for a proper AEM implementation.
D. Manually recreating over 20,000 pages would be extremely slow, expensive, and error-prone, directly contradicting the requirement to complete the migration quickly.

This guide discusses various tools and strategies, where ETL is a primary method for structured content. The implicit recommendation is to handle exceptions or unstructured content separately, often manually.
