I’ve been through this path recently - and using rolling_upgrade playbook from stable-4.0
worked just fine.

For previous Ceph version upgrades, we've used the rolling_upgrade playbook from
Ceph-ansible - for example, the stable-3.0 branch supports both Jewel and Luminous, so we
used it to migrate our clusters from Jewel to Luminous.
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?
