As I understand it, upgrading direct from Luminous to Nautilus is a supported operation. But there is no Ceph-ansible release that supports both versions. Indeed, stable-4.0 supports Nautilus but no other releases. Is the expected process to use stable-4.0 for the upgrade, or do we have to do the upgrade by hand and only then update our version of ceph-ansible?
