   Hi,
   
   Now we are running druid 0.13.0-incubating as single-server deployments.
   Our goal is to migrate current setup in to  druid Cluster setup ( V :
   0.16.0-incubating)
   
   First we try to migrate 0.13.0 to 0.16.0 single-server and there is a
   problem when migrating deep-storage because the structure has been changed
   from 0.13 to 0.16. ( In current version 0.13.0,  there are two files in
   segments  *descriptor.json & index.zip  *But in new version 0.16.0
   *descriptor.json* is not there ). Also when we copy the segments in to new
   location still it is searching for old path.
   
   Also we used Export Metadata Tool to migrate  durby metadate in to
   Postgress in clusterd environment and it was success.
   But We were unable to find  a way to migrate deep storage in to clustered
   environment.  We are using Azure blob storage as deep storage and your
   documentation only provide some
    details on migrate to S3 but still not clear. ( means there is no other
   tool than export metadata tool)
   
   So we would like to know what is the best way to follow to migrate data
   from druid 0.13.0-incubating single-server deployment to druid
   0.16.0-incubating Clustered deployment.
   
   Thanks
   Gayan
