Hello,

I have free space between two slices to I tried to do the same as you.

When you have the image of a slice generated by 'dd', it contains its
partitions and filesystems. First you may want to make that slice image
(file) to appear in '/dev', so you can manipulate its partitions. This
is done (in FreeBSD 5.X, if you use 4.X use'vnconfig', there are
examples in the Handbook) like with a CD-ROM ISO image (see the
Handbook->Storage):

mdconfig -a -t vnode -f <file> -u <n>

It will appear in '/dev' as 'md<n>', with its partitions, like the
following:

md1a
md1c
[...]

So you can mount them, dump them, etc., like with a slice (in fact,
it is an image of a slice).

When you end what you want to do with it, do (after unmounting the
partitions):

mdconfig -d -u <n>

Best Regards,
Ale
