most efficient method to transfer disk-to-disk

I am embarking on a mail store transfer tonight between ufs and vxfs.
Tar has a large overhead while ufsdump is obviously not an option.
These disks are both local (fcal san attached) so no network issues
involved.

I am thinking a combination of ufsdump piped to dd might be the most
efficient but I don't know this for sure and I also do not know the
syntax for such a transfer.

Looking for suggestions and syntax. FYI; filesystems are /webdata and
/mail_data (/webdata is the current ufs file system).

Thanks.
