I have 9TB " CIFS and NFS data " in R200 , I want move this data to the new system FAS2050.
What the best way to move this data.?
Can I connect the two systems together thru fiber ? ,how can I achieve that,
Best Regards

You can move the physical disks from one head to the other, but that will only work if:
1. You have a traditional volume or 2. You have an aggregate that contains ONLY the volumes you want to move.
Unplug the disks from the original filer, and plug them back into the new one, the new disks with the data on it will be recognised, and you can force them online.
If you cannot move the disks, because for instance you also have your root volume or other data in an aggregate, you can copy the data (this will take a while..)
You can use ndmpcopy to do this. By using ndmpcopy, you in essence perform a backup/restore over the network, with the same speeds that an NDMP backup from a filer usually has.
One disadvantage of this, is that you won't transfer snapshots and retain the snapshot metadata (such as date of the snapshot etc). If that's important to you, you might consider a SnapMirror license. You will need one on both heads. I think that for migration scenario's time limited licenses are available.

As said above, you can move the disks. I haven't tried to make one NetApp FCP initiator and the other FCP target yet, but it would be an interesting experiment :)

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.

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,
