Once I got it built, the tool seemed quite nice. The speeds I was seeing were about 500K/sec (at best). But, the source filer is quite busy. There were some very odd problems with the ndmpcopy. It simply stopped once (that sucked). This was after having spent 3 hours getting to that point (and 10 hours left, according to the program). Not very happy when that occured.

Sounds great. My only question (which I think was answered by Beepy) was if you can run the tool while still serving data? The only reason I did not pursue the BMM was that I could not afford any downtime. I hope that future migrations will be less painful. (well, at least faster).

Thanks for the reply. I have found it quite interesting.
