I have done this using Clonezilla to clone from one partition to the
other.  I do not use UUIDs for booting now - I have labels on the
drives and use LABEL=xxxxx instead of UUID=xxxx in fstab.  That makes
the process not too difficult.  First, make sure that you are using
something other than UUID in the existing boot partition's fstab.  You
can add labels to partitions using GParted, or just use a direct
/dev/sdx setup in fstab.  Run update-grub.  Then boot Clonezilla and
tell it to do the cloning.  Boot into the existing partition again,
and change the UUID of the new partition.  Give it a label as well.
Here is how to change the UUID:

Once you have different UUIDs, run update-grub so that it can set up
booting for the new partition.  Mount the new partition temporarily
and edit its fstab to point the boot partition to the new partition,
using its new label.  Then reboot and select your new partition to
boot.

Remember that whenever you update anything affecting booting on the
new partition (eg an update installs a new kernel), you will need to
reboot to the original boot partition and run update-grub from there
before the changes will work.
