The easiest solution, that also demands minimal downtime is using ndmpcopy/rsync altogether...
This will work only if you have free volumes on the new machine...
1. Copy a baseline copy of the seperate parts of your current volume to the target volumes, using ndmpcopy/rsync/tar/whatever (ndmpcopy will be the fastest probably). This can be done while users are working, a few hours/days before the migration downtime is planned. 2. In something like a few hours before the downtime, use the utility "rsync" and/or ndmpcopy to copy incrementally the changes since the baseline. 3. DOWNTIME - while in downtime, just do a final syncing, again using ndmpcopy incremental/rsync, and change the relevant settings: NIS maps, filer's /etc/exports, /etc/quotas...
