ok, you have options. You can use nas_copy command to copy data from file system created on performance pool to file system created on archive pool. Target file system has to be identical size, or you can use server_archive command to do the same but target file system does not have to be identical size. Either option will preserve NTFS ACLs. Once you copy data from source to target file system, you simply unmount old file system and remount the new file system under the same mount point name, this way you don't have to mess with shares or anything like that.
Hello -  A customer has an EMC Celerra NS-20 head on a Clariion CX3-10.  They have a large CIFS share that is 990GB (see picture).  The customer has chosen to purchase additonal disk, and would like to move the large CIFS share in the current Performance Pool to other disk.   I am assuming that the new disk is already installed and even presented to the NAS as a new storage pool.  What would be the best way to migrate this large CIFS File System over to a new storage pool, maintaining Windows ACLs and limiting customer downtime?  Sven
