I'm running a three node 3.4 cluster with integrated ceph server.
Upgrading another test cluster showed that one has to be very careful as you have to create a new cluster. So I have some questions:

Upgrading another test cluster showed that one has to be very careful as you have to create a new cluster. So I have some questions:
- Did anybody already upgrade a running 3.4 ceph cluster to 4.0?
- Will I loose my ceph configuration?
- What is the right order of steps to not fully loose the ceph cluster and all its OSDs (if possible)?
