I am guessing that you are trying to update a virtual machine. If this is the case then you can try the following.

  1. Boot your CentOS 5.8 VM using the CentOS6 ISO
  2. On the initial screen press tab

  3. when the boot command appears, append upgradeany

    vmlinuz initrd=initrd.img upgradeany

When you pass the language and devices selections and the system is done examining the storage, you will be prompted if you want to upgrade an existing installation and be shown a drop down list of versions that were found.
