It's not possible. NDMP is just a wrapper around the vendor specific dump/restore tools. I find this annoying too, but it's better than nothing.
Basically, the Netapp is just using the regular netapp 'dump' command but instead of going to a local tape drive, it's going to an NDMP target (which *can* be a local FC tape drive, but not a SCSI one as I recall) or can be over the network to another block device which understands NDMP.
The protocol then sends an index stream of to the controlling NDMP process so it can see which file(s) are backed up.
This is also why you can't do a full NDMP backup, and then unlimited incrementals for a month. You need to make sure you have weekly differential backups in the mix as well, since Netapp dump is really just old style unix dump with upto nine levels of backups.
Does this answer you're question?
The only way you'll make this work is mount the Netapp filesystem onto a system which also mount the Oracle ZS3 filesystem and then use tar or rsync or even just 'cp -r ....' to move the data.
