Hi all, We're planning to upgrade an existing testing 14.2.6 CEPH cluster to latest 15.2.4. Existing cluster was deployed using ceph-ansible and we're still searching steps to do the upgrade. Shall we do the upgrade with steps like following ? - Upgrade rpm on all nodes (mon/mgr first, then osd, then rgw) - Convert the cluster to use cephadm as mentioned here https://docs.ceph.com/docs/master/cephadm/adoption/ Apology for the newbie question. Thanks a lot. Regards, /ST Wong
