I just want the latest minor version before upgrading to the next major version 
:) This practice isn't recommended elsewhere, but I want to make sure and limit 
errors as much as possible.

I have upgraded dozens of clusters 14 -> 16 using the methods described in
the docs, and when followed precisely no issues have arisen. I would
suggest moving to a release that is receiving backports still (pacific or
quincy). The important aspects are only doing one system at a time. In the
case of monitors ensuring it rejoins quorum after restarting on new version
before proceeding to next mon. In the case of OSDs waiting for all PGs to
be active+clean* before proceeding to the next host.

Yes, the documents show an example of upgrading from Nautilus to Pacific. But 
I'm not really 100% trusting the Ceph documents, and I'm also afraid of what if 
Nautilus is not compatible with Pacific in some operations of monitor or osd =)

Curious, why not go to Pacific? You can upgrade up to 2 major releases in a
go.

The upgrade process to pacific is here:
https://docs.ceph.com/en/latest/releases/pacific/#upgrading-non-cephadm-clusters
The upgrade to Octopus is here:
https://docs.ceph.com/en/latest/releases/octopus/#upgrading-from-mimic-or-nautilus

Maybe check the changelog, check upgrading notes, and continuosly monitor the 
mailing list?
I have to do the same upgrade and eg. I need to recreate one monitor so it has 
the rocksdb before upgrading.
