Overview

The Content Transfer Tool is a tool developed by Adobe that can be used to move existing content over from a source AEM instance (on-premise or AMS) to the target AEM Cloud Service instance.

This tool also transfers principals (users or groups) automatically.

Phases in Content Transfer Tool

There are two phases associated with content transfer:

  1. Extraction: Extraction refers to extracting content from the source AEM instance into a temporary area called migration set. A migration set is a cloud storage area provided by Adobe to temporarily store the transferred content between the source AEM instance and the Cloud Service AEM instance.

    Refer to Extraction Process in Content Transfer for more details.

    NOTE

    It is recommended to run the User Mapping Tool as part of the Extraction phase. See Using User Mapping Tool for more details.

  2. Ingestion: Ingestion refers to ingesting content from the migration set into the target Cloud Service instance.

    See Ingestion Process in Content Transfer for more details.

Attributes of a Migration Set

A migration set has the following attributes:

  • A maximum of ten migration sets can be created and maintained at a time during the content transfer activity.
  • Each migration set should have a unique name.
  • If a migration set has been inactive for more than 30 days, it will be automatically deleted.
  • Whenever you create a migration set, it is associated with a specific environment. You can only ingest into an author or a publish instance of the same environment.

The Content Transfer Tool has a feature that supports differential content top-up where it is possible to transfer only changes made since the previous content transfer activity.

NOTE

After the initial content transfer, it is recommended to do frequent differential content top-ups to shorten the content freeze period for the final differential content transfer before going live on Cloud Service.

In the extraction phase, to top-up an existing migration set, the overwrite option must be disabled. Refer to Top Up Extraction for more details.

In the ingestion phase, to apply the delta content on top of the current content, the wipe option must be disabled. Refer to Top Up Ingestion for more details.
