Maybe CD upgrades would work from old CDs but the machine is externally hosted so that's not an (easy) option, although maybe that could be achieved.
Not suggesting that you do this, but if you can get/manufacture ISO images of the old update disks, you could mount the ISO files as a fake cd drive and run the update from said fake drive. Mounting the ISO is as simple as right clicking on in a file manager and chosing Disk Image Mounter (at least it is on my version of Lubuntu).
