Introduction
When a domain is marked for deletion, the job DeleteDomainReferences deletes all references to that domain. Similarly, if a user is marked for deletion, the job DeleteUserReferences deletes all references to that user. Currently, the configured DomainDeletionPipeline or the corresponding UserDeletionPipeline are called in each cartridge. These pipeline calls still work, but they have been marked as deprecated and will be removed. Instead, use the Guice Multibinder to bind DomainReferenceDeletionHandler or accordingly UserReferenceDeletionHandler as described in Concept - Mass Data Cleanup.
Migration for Each Cartridge
Domain Reference Deletion
The migration is only needed if DomainDeletionPipeline is used in the cartridge.
Cartridge Properties
In the cartridge properties file, remove the DomainDeletionPipeline configuration.
Add Cartridge-Specific Domain Reference Deletion Handler
Afterwards, add and bind a cartridge-specific domain reference deletion handler as described in Cookbook - Mass Data Cleanup | Recipe: Add and Bind a Cartridge-Specific Domain Reference Deletion Handler, which is the replacement for the removed pipeline from the properties file. In that new domain reference deletion handler, you can migrate the previous pipeline execution for the domain reference deletion handling of the cartridge.
User Reference Deletion
The migration is only needed if UserDeletionPipeline is used in the cartridge.
Cartridge Properties
In the cartridge properties file, remove the UserDeletionPipeline configuration.
Add Cartridge-Specific User Reference Deletion Handler
Afterwards, add and bind a cartridge-specific user reference deletion handler similar to domains as described in Cookbook - Mass Data Cleanup | Recipe: Add and Bind a Cartridge-Specific Domain Reference Deletion Handler, which is the replacement for the removed pipeline from the properties file. In that new user reference deletion handler, you can migrate the previous pipeline execution for the user reference deletion handling of the cartridge.
