Tmac,
Careful - using cp or rsync from a Unix host will strip the ACL's from any NTFS volumes/qtrees he may have - remember he said "CIFS and NFS data".
Hisham,
NDMPcopy or vol copy over GigE are both fine if your data volumes can be offline to the users during the entire migration period.
You can also use the "foreign volume local vol copy" method by temporarily attaching a shelf from one filer to the other, but that involves very careful planning, although it is the fastest way to move the data.
However, if you want to be able to do most of the migration while your systems are live, you have a couple of options:
1. SnapMirror in the background, then plan a user outage for the final sync interval before breaking the mirror. This requires a licence, which may be too expensive for the occasional data migration.
2. rsync for the unix data, and a product like "Secure Copy" from Script Logic that can do the same thing for Windows data while preserving the ACL's (this also has options for local group to global group translation for moving data of old Windows file servers). Again, you still need a user outage for the final sync.
Hope this helps,

A couple of choices.
Depending on your release of ONTAP, you could just cross-connect them with GigE and run a vol copy. This is a low-level copy of a volume and is quite fast. It does not care about quantity or size of files since it is working at a block level.
You need to create the same volume type to do a vol copy. I.E. flex to flex or trad to trad. You cannot copy flex to trad or trad to flex.
Should your release not support your 9TB volume, then you will be stuck with either: NDMPcopy or a copy program (like cp or rsync) from a UNIX host. Don't bother with Windows, too slow.

What the best way to move this data.?
Can I connect the two systems together thru fiber ? ,how can I achieve
that,
