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
Francois Scheurer
