I would use rsync; over NFS if possible otherwise over ssh:
(NFS performs significantly better on read than write so preferably share from
the old and mount on the new)
old# share -F nfs -o [EMAIL PROTECTED],[EMAIL PROTECTED] /my/data
(or edit /etc/dfs/dfstab and shareall)
new# mount -r
Sorry I realize I was a bit misleading in the path handling and need to correct
this part:
new# mount -r old:/my/data /mnt
new# mkdir -p /my/data
new# cd /mnt ; rsync -aRHDn --delete ./ /my/data/
new# cd /mnt ; rsync -aRHD --delete ./ /my/data/
new# umount /mnt
..
new# cd /mnt ; rsync -aRHD
