Upgrade Sequencing
~~~~~~~~~~~~~~~~~~
It is possible to do a rolling upgrade from Cuttlefish to Dumpling.
#. Upgrade ceph-common on all nodes that will use the cli
#. Upgrade all monitors (upgrade ceph package, restart ceph-mon
daemons). This can happen one daemon or host at a time. Note that
because cuttlefish and dumpling monitors can't talk to each other,
all monitors should be upgraded in relatively short succession to
minimize the risk that an a untimely failure will reduce
availability.
#. Upgrade all osds (upgrade ceph package, restart ceph-osd daemons).
This can happen one daemon or host at a time.
#. Upgrade radosgw (upgrade radosgw package, restart radosgw daemons).
Upgrading from v0.66
