I'm working on a project in which there is a particular use-case to prevent the deletion of content from migrating to a target instance of WebCenter Content. Normally, when automatic replication is configured between instances of WebCenter Content, every action is replicated between environments; check in, update, & delete. But in this particular case they wanted check ins and updates to be migrated, but not deletes.
Archiver does not have any built-in options or toggles to control what actions get replicated, but it turns out you can control this as part of the export query configuration. To set this, go to the Export Query and select the field of Revision Status. This specifies all of the states a document goes through in its lifecycle. Set the Operator to 'Is Not' and select 'Deleted' from the Value list. Add this to the rest of the query and now deletes won't be propagated.
