The key part is changing the monitors addresses: http://docs.ceph.com/docs/luminous/rados/operations/add-or-rm-mons/#changing-a-monitor-s-ip-address Once your mons are happy with their new addresses, you can just update ceph.conf for the rest of the services (including OSDs). By the way, I notice you're an 11.x version, which is EOL. It would be wise to update your cluster to the 12.x ("luminous") stable series before doing the address updates; that way if you run into any issues you'll be using a version that's better tested and more familiar to everyone.
