(I Should have read a little furthur). If I remember, I think that
copying directly to larger HD is fine (I think the last partition picks
up any extra space. But don't quote me on that).  If its smaller you
will have to do some finagling or use a different tool (I don't know
what though).

You can use tar in the capacity that you described if you make the
partitions on the destination server ahead-of-time and then copy (so,
this will work with different sized hard drives as long as the contents
of a source partition aren't larger than the space alotted in the
destination partition):

tar -cf - /mountpoint/for/partion/* |gzip -c -9 |ssh server "tar zxvf -
-C /your/new/mountpoint"
