Migrating content between enterprise content management systems is described. A source object identifier is identified for metadata tables for content for a source enterprise content management system, based on a migration job definition. The metadata tables are retrieved from the source enterprise content management system, based on the source object identifier. A target object identifier is identified for a target enterprise content management system, based on the metadata tables and the migration job definition. An object identifier map is created that maps the source object identifier to the target object identifier. The metadata tables are stored to the target enterprise content management system, based on the object identifier map. The content for the source enterprise content management system is retrieved. The content is stored as content for the target enterprise content management system.
