When you click on 'Apply' to take effect the copy, please tick on 'Shut down the computer after changes are applied'. Please do not power on your computer with both source and destination disks connected as this may cause boot trouble.
After you boot from the destination disk normally, you can try to extend the partition C with unallocated space on the new disk.
