Hi,
no, you can't go directly from O to R, you need to upgrade to Q first.
Technically it might be possible but it's not supported.
Your approach to first adopt the cluster by cephadm is my preferred
way as well.

Hi ceph-users,
I currently use Ceph Octopus to provide CephFS & S3 Storage for our
app servers, deployed in containers by ceph-ansible. I'm planning to
take an upgrade to get off Ceph Octopus as it's EOL.
I'd love to go straight to reef, but vaguely remember reading a
statement that only two major versions can be taken on upgrade. I've
failed to find that statement again.
Is it possible to go directly from Octopus straight to Reef?
I think a sensible approach here is to first migrate our existing
deployments to use cephadm, and then use cephadm to upgrade. Any
advice on this very welcome.
Many thanks,
Alex
