Tar really handles this well.  Use that but leave out /proc and tmp.  
Then untar in your new location, and modify your grub to reflect.  Do a 
search for this in google ( tar proc system backup etc... ) and there 
are several howto's

Good luck.  Also it may be a good idea to make another stanza in your 
grub to reflect the new partition and leave the original in place for 
now.  That way you always have your original setup there until you get 
it working ok..
