Hi David;
some input to get back to where you were : a) Start with the French cluster
only and get it working with DSE 4.5.1 b) Opscenter keyspace is by default RF1;
alter the keyspace to RF3 c) Take a full snapshot of all your nodes & copy
the files to a safe location on all the nodes
To migrate the data into new cluster: a) Use the same version DSE 4.5.1 in
Luxembourg & bring up 1 node at a time. Check that the node has comeup in
the new Datacenter.b) Bring up new nodes into the new Datacenter one at a
timec) After all your new nodes are UP in Luxembourg, conduct a 'nodetool
repair -parallel' d) Check in OpsCenter that you have all your nodes
showing up (new and old)e) Start taking down your nodes in France, one at a
timef) After all the nodes in France are down, conduct a 'nodetool repair
-parallel' again g) Upgrade the nodes in Luxembourg to DSE 4.6.1 h) conduct a
'nodetool repair -parallel' again i) Upgrade to OpsCenter 5.1
Best of luck, hope this helps.

other country)
This is officially unsupported, and might cause of problems during this process.
