[ceph-users] Upgrade Ceph cluster + radosgw from 14.2.18 to latest 15

Hi, I want to upgrade my old Ceph cluster + Radosgw from v14 to v15. But I'm not using cephadm and I'm not sure how to limit errors as much as possible during the upgrade process? Here is my upgrade steps: Firstly, upgrade from 14.2.18 to 14.2.22 (latest nautilus version) Then, upgrade it from 14.2.22 to 15.2.17 (latest octopus version) service restart order: - restart monitors (sleep ~10) - restart managers (sleep ~5) - restart metadata OSDs (sleep ~30) - restart data OSDs (sleep ~30) - restart radosgw (sleep ~20) Is there anything wrong with these steps? Does 15.2.17 is the most stable version of Octopus? Thanks.
