Hi,
first of all, the Ceph docs are "official", here's the relevant
section for upgrading Ceph:
https://docs.ceph.com/en/latest/cephadm/upgrade/
Octopus was the first version using the orchestrator, not Pacific. So
you could adopt your cluster to cephadm in your current version already:
https://docs.ceph.com/en/octopus/cephadm/adoption/
There are many people on this list (and probably off list, too) who
don't really like the orchestrator, or don't like containers etc. It
will require some time to get used to it, but I find the benefits
worth it. One of them being able to upgrade your cluster without
touching the host OS. I would recommend to get some practice in a lab
cluster and familiarize yourself with cephadm before practicing on a
production environment. ;-)
One of the questions that arise is whether the clients (depending on
the OpenStack version) in Octopus and the mons, mrgs, osds, mds etc.
etc. in Pacific/Quincy will function correctly.
Note that Quincy is already EOL, you could go from Pacific to Reef
directly (18.2.5 will be released soon). You could also go from
Octopus to Quincy and then Squid, all those upgrade paths are safe and
supported. Your OpenStack clients should also work fine with a newer
Ceph cluster, just recently I upgraded a customer Ceph cluster to Reef
while their OpenStack clients are still on Octopus, and there haven't
been any complaints yet.
Hope this helps!

Zitat von Iban Cabrillo <cabri...@ifca.unican.es>:
Dear cephers,
We intend to begin the migration of our Ceph cluster from Octopus to
Pacific and subsequently to Quincy. I have seen that from Pacific
onwards, it is possible to automate installations with cephadm.
One of the questions that arise is whether the clients (depending on
the OpenStack version) in Octopus and the mons, mrgs, osds, mds etc.
etc. in Pacific/Quincy will function correctly.
The second is whether it is feasible, advisable to switch to
cephadm/orch, since I have always performed updates manually for
many, many years.
And the third, if there is any 'official' guide available for these updates.
Thanks in advance, I
