If you want to upgrade from CD then you'll have to use the Alternate CD[1].
This is because on the Live CD the packages are installed in to the
squashfs file and are just copped over to the install system. There are
some packages on the Live CD in the repository on the disk, but not the
whole system. The alternate CD has all the packages on the disk so you
can use that.
Also note that only the packages in the main and restricted repository
will be upgraded from the CD, so if you have any universe or multiverse
packages installed then you will have to download the updates of them.
Also I don't think ALL the packages in the main and restricted
repository's are on the disk anyway, so you'll have to download some.
