I'd use dump and restore for this, something like:

dump -0 -f - /smalldisk | (cd /bigdisk; restore -r -f -)

Both filesystems must be the same type, and the new one must really be
new.  newfs it just before doing this, just to be on the safe side.

cp will *not* do the job.

Ideally, you'll be in single user mode when you run the dump/restore.
It is essential that no other processes are using those filesystems
anyway.
