One issue that you may run into is that the UUID of the disks will not be the 
same, so without modifying the boot files, the system will not work.

Generally, I just clone the old disk to the new disk using a livecd with G4L, 
which I am the maintaner of, or other ones like clonezilla or G4U. That will 
give you the same size partitions on the new disk, but you can then use other 
programs like gparted or LVM utilities to use the extra space.

I recently cloned an 80G disk to a 1T disk with no issues, and since the clone 
process uses dd to copy the raw data, all the links and other issues are not a 
problem.
