No, this is not supported. You must follow the upgrade order for
services. The reason is that many parts of RGW are implemented in the
OSD themselves, so you can't run a new RGW against an old OSD.

Dear All
One ceph cluster is running with all daemons (mon, mgr, osd, rgw) having the version
12.2.12.
Let's say we configure an additional radosgw instance with version 14.2.8, configured
with the same ceph cluster name, realm, zonegroup and zone as the existing instances.
Is it dangerous to start a different version of rgw concurrently with the older rgw?
Can both versions server PUT & GET requests concurrently on the same buckets?
It is probably ok, because during an upgrade it is as well assumed to have temporarily
different versions running concurrently...
So the question is kind of the same as asking if one may cancel the radosgw upgrade from
Luminous to Nautilus in the middle, rolling back the radosgw packages.
Many thanks in advance.
Cheers
