An architect plans to migrate the user and groups from an existing AEM instance to an AEM as a Cloud Service (AEMaaCS) instance. The migration…

The scenario requires starting the migration with a "clean repository" and a "reset of all user permissions." The Content Transfer Tool (CTT) provides a specific option for this purpose. Enabling the "Wipe existing content on Cloud instance before ingestion" option instructs the CTT to delete all content and user data from the target AEMaaCS repository before the new content is ingested. This action ensures that the migration starts on a clean slate, preventing conflicts with pre-existing data and fulfilling the stated requirements directly and efficiently.

A. An ACL package with option="Merge" would add or combine permissions with existing ones, which contradicts the requirement to reset permissions and start with a clean repository.
B. Disabling the "Wipe" option would cause the CTT to merge the migrated content with any existing content on the cloud instance, which is the opposite of the stated goal.
C. An ACL package with mode="replace" would replace existing ACLs on matching paths but would not create a "clean repository" by removing all other content and users.

1. Adobe Experience Manager as a Cloud Service Documentation, "Tools - Content Transfer Tool - Ingesting Content into the Target". In the section describing the ingestion job, the documentation details the "Wipe existing content on Cloud instance before ingestion" option. It states that when this option is selected, "all existing repository content in the target Cloud Service instance will be deleted before ingestion starts."

2. Adobe Experience Manager as a Cloud Service Documentation, "Tools - Content Transfer Tool - Best Practices". The guide recommends using the wipe feature for the initial full migration to ensure a clean environment, stating, "For initial extraction and ingestion, it is recommended to perform a full extraction and ingestion with the wipe option enabled on the cloud instance."
