I migrated the majority of the data on our F740 to our F820 this past August. Total data was ~200GB, and a mixture of qtrees and plain subdirs. I set up a private GigE connection between the two, and used ndmpcopy across that. Total time to copy over was just shy of 9 hours. The F740 was still serving data (read-only) for that time (midnight-9am, so not a very high load).
In the tests I ran from our F810 to the F820 across private GigE (both machines basically idle), the transfer was about 50% faster.

I am contemplating moving an entire filer from 18 GB drives (many, many problems) to 36 GB drives; the reasons are an entirely separate posting. My question is, what is the fastest, most reliable way to move the data? This past weekend, I moved about 100 GB in four different qtrees with ndmpcopy, and each qtree averaged about 40 hours to move (between 34 to 44 hours). I am looking at moving three times that amount of data on this other filer. I seem to recall using snapmirror or snaprestore when we migrated from an F630 to our F760C, but that was quite some time ago. I was wondering if anyone had stories, recommendations, pointers on what is the best method to transfer data.
Thanks to all in advance!
