First tar /opt in a tarfile on your other disk
ex : cd /opt
tar cf - . | (cd /newdisk; tar xpvf -)
compare the size of the two file systems, if they are equal
unmount /newdisk
unmount /opt
then modify /etc/vfstab to reflect the change for /opt
mount /opt.
Hope this helps

How about this?
mkdir /a
mount /dev/dsk/c0t1d0s4 /a
account for vfstab
Can you make the change to vfstab first before you unmount the filesystem?
unmount /newdisk
unmount /opt
then modify /etc/vfstab to reflect the change for /opt
mount /opt.

With the mount procedure you are not moving the filesystem
off one disk to another. the data is still on the original disk - you are just changing where it appears to be by changing the mount point.
"cp" or the "find" command works well for moving data. With the find command use -print and pipe it to cpio. Check the man pages on cpio for options (I use -pdlumv).
After the copy , compare records - I use "du -k".
Still make your vfstab changes as above.
Hope this helps
