The katello-disconnected server synchronization and export functions are being moved into the Satellite server itself. With 6.2, the katello-disconnected command will no longer be delivered and instead will be replaced with a new export and import functions delivered via the UI and hammer CLI. This bug is being closed as "WONTFIX" since it relates only to the existing katello-disconnected tooling. Please check the Satellite docs with the release of Satellite 6.2 on how to use the new content export and import features.
