Agreed.  That tool would be gparted.  And if you use it to resize the
partition, you might as well use it to copy the data as well.   I too
thought that Clonezilla and/or dd would be the easiest.  In the end it
was gparted.  Prior to this I had never thought of gparted as a cloning

For those that aren't aware, gparted is VERY good at moving and resizing

Actually, it didn't.  I'm not sure why and I don't have time to figure
out why.  I think you need to do something with the MBR too. 

In short, my advice to anyone who needs to do this is to use gparted.
