[ceph-users] Upgrading Ceph 15 to 18

Hello, we'd like to upgrade our cluster from the latest Ceph 15 to Ceph 18. It's running with cephadm. What's the right way to do it? Latest Ceph 15 to latest 16 and then to the latest 17 and then the latest 18? Does that work? Or is it possible to jump from the latest Ceph 16 to the latest Ceph 18? Latest Ceph 15 -> latest Ceph 16 -> latest Ceph 18. Best, Malte
