Objet: [ceph-users] Migrating from one Ceph cluster to another


I have a ceph cluster (Hammer) and I just built a new cluster (Infernalis). 
This cluster contains VM boxes based on KVM. 

What I would like to do is move all the data from one ceph cluster to another. 
However the only way I could find from my google searches would be to move each 
image to local disk, copy this image across to new cluster, and import it. 

I am hoping that there is a way to just synch the data (and I do realize that 
KVMs will have to be down for the full migration) from one cluster to another. 

Thank you
