I can't speak for RBD, but for RGW, as long as you upgrade all the RGWs
themselves, clients will be fine, since they speak S3 to the RGWs, not
RADOS.

Dear all
I am going to update a ceph cluster (where I am using only rbd and rgw,
i.e. I didn't deploy cephfs) from Octtopus to Quincy
Before doing that I would like to understand if some old nautilus clients
(that I can't update for several reasons) will still be able to connect
In general: I am not able to find this information in the documentation of
any ceph release
Should I refer to get-require-min-compat-client ?
Now in my Octopus cluster I see:
[root@ceph-mon-01 ~]# ceph osd get-require-min-compat-client
luminous
but I have the feeling that this value is simply the one I set a while ago
to support the upmap feature
Thanks, Massimo
