6.26 (x86 Only) Oracle VM Server Upgrade From CDROM Not Supported For Releases Prior to 3.3

Upgrading an x86 Oracle VM Server directly from CDROM is not supported when attempting to upgrade from a release prior to a 3.3 release. Upgrades from previous releases are complex and require transitional steps that are handled using an upgrade script, and which require you to configure and set up the yum repositories that are needed to complete an upgrade of this type. The full process is documented in the Oracle VM Installation and Upgrade Guide.
