It depends on the answer to the question above. If FreeBSD can read the NetBSD version of UFS but there is some header/partitioning data in the way, there is an example of skipping over that in mdconfig(8). If NetBSD can read and write FreeBSD UFS, then add another drive with FreeBSD UFS to the NetBSD system and copy it there. If it is something only NetBSD can read, a NetBSD VM on a FreeBSD host could deal with it. scp/rsync/cpdup could be used. That will go through the VM-to-host network. In theory, that would be faster than a physical network. In practice, it might not be any faster.
