Deprecated and Removed Features deprecated-and-removed-features
Adobe continually reviews product capabilities to improve customer value by modernizing or replacing older features. These changes are made with careful attention to backward compatibility.
To communicate the impending removal or replacement of Adobe Experience Manager (AEM) capabilities, the following rules apply:
- Announcement of deprecation comes first. While deprecated, capabilities are still available but are not further enhanced.
- Removal of deprecated capabilities occurs in the following major release at the earliest. The actual target date for removal is planned for announcement later.
This process gives customers at least one release cycle to adapt their implementation to a new version or successor of a deprecated capability, before actual removal.
Deprecated features deprecated-features

Customers are advised to review if they use the feature/capability in their current deployment, and make plans to change their implementation to use the alternative provided.
