Has anyone used ndmpcopy to migrate volumes from ontap 6.5 to 8.1 without going through any intermediate steps? The 8.1 docs say qtree snapmirror doesn't support source volumes prior to 6.5, so I'm looking for success stories on possible alternatives in case it doesn't work as advertised.
rsync takes a long long time, but it works fine. This is all linux data, nfs.

In my experienced opinion (I have gone from ONTAP 7 ->GX, also from GX -> ONTAP 8, 7-mode, and now getting ready to do a 8.1 7-mode to 8.1 c-mode transition)
In the early days, rsync was bad. It was single threaded and you had to wait to parse the entire directory tree. (pre-3.0) In the new rsync (3.0 and higher), it is multi-threaded and a significant speed increase. It starts copying data sooner. (I typically do rsync -avHP /source/vol/ /dest/vol/ -> notice the trailing slashes....)
ndmpcopy may be hairy and tricky. there were some issues back in 6.x that were never fixed. The incremental support is not all that good. You can keep on going with plenty of rsyncs to refresh.

Follow up: Qtree snapmirror from 6.5 to 8.1 was the method we used. It worked great but took a bit longer than I expected to mirror 1TB. The F840 wasn't overloaded by the transfer, and the 2240-2 absorbed the data with ease.
Thanks to those who replied for the input. -Jon

Bit frustrated here. When I go to follow the KB ID 1012673 to turn on the disabled counters for the PAMII card, right before I click finish under setup > host>, I get an error that the default ports are not open (8488) which they were. The reason I am getting the error is the DFM SERVER service crashes with this:
I have followed the instructions to the letter in the kb article. I have DFM 5.0 and the host I am trying to turn the counters on for ranges from DOT 8.0 to 8.1.. Same error.

Figured I would send out what support came back with..
I had to upload my database to netapp support, and I had a specific scheduled report in DFM that was causing the issue.. I removed the report, and boom, works..
