Hi, 

 When migrating a NON-NTFS disk from IS datastore to another IS datastore, onapp do use "dd" with bs=4096 which may result in non-optimal performance.  For large disk, it may take very long(e.g. > 450hrs) for completing such task. 

 Would you please consider using filesystem aware tools(like partclone) for the cloning or increase the bs value in dd? 

Thanks,
Steven Wong

  The block size has been added as a configurable option in OnApp 5.4. For more details refer to the following doc:  https://docs.onapp.com/display/54AG/Edit+System+Configuration
