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
