Andrei, that is not true. CS will not automatically copy all the data from existing NFS to the new NFS added, only for those templates that are cross-zone. NFS to S3 migration is not done that way either, actually is done on demand. Please see https://cwiki.apache.org/confluence/display/CLOUDSTACK/Migration+of+NFS+Sec ondary+Storage+to+Object+Store for detailed implementation in 4.2.1.
