If the cluster is managed by cephadm you should be able to just do a "ceph orch upgrade start --image quay.io/ceph/ceph:v16.2.7". We test upgrades from 15.2.0 to pacific and quincy so I think going from 15.2.5 to 16.2.7 directly should work. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
