[ceph-users] upgrade ceph and use cephadm - rgw issue

Hi I am trying to upgrade from Mimic (13.2.10) to Octopus (15.x).   Im also tryin to sue cephadm and am following this guide.https://docs.ceph.com/docs/master/cephadm/adoption/ It was all going fine until step 11 and deploying the new RGW's.  I don't have any realms set for my cluster, so how do I do it? This is also a single site cluster. # radosgw-admin realm list{    "default_info": "",    "realms": []} # radosgw-admin zone list{    "default_info": "a15e2aec-a0da-4cad-a1bd-f448f25bbe3d",    "zones": [        "default"    ]} The step below is what I don't know what to do, as it says I need to specify the realm. 11. Redeploy RGW daemons. Cephadm manages RGW daemons by zone. For each zone, deploy new RGW daemons with cephadm: # ceph orch apply rgw <realm> <zone> <placement> [--port <port>] [--ssl] my ceph.conf has this in it about the rgw's[client.rgw.ceph-mgmt0]host = ceph-mgmt0keyring = /var/lib/ceph/radosgw/ceph-rgw.ceph-mgmt0/keyringlog file = /var/log/ceph/ceph-rgw-ceph-mgmt0.logrgw frontends = civetweb port=10.92.135.40:8080 num_threads=100rgw dns name = library.xxxxx.com [client.rgw.ceph-mgmt1]host = ceph-mgmt1keyring = /var/lib/ceph/radosgw/ceph-rgw.ceph-mgmt1/keyringlog file = /var/log/ceph/ceph-rgw-ceph-mgmt1.logrgw frontends = civetweb port=10.92.135.41:8080 num_threads=100rgw dns name = library.xxxxx.com [client.rgw.ceph-mgmt2]host = ceph-mgmt2keyring = /var/lib/ceph/radosgw/ceph-rgw.ceph-mgmt2/keyringlog file = /var/log/ceph/ceph-rgw-ceph-mgmt2.logrgw frontends = civetweb port=10.92.135.42:8080 num_threads=100rgw dns name = library.xxxxx.com RegardsAndy
