Issue With Migration From RHN To RHSM

Currently using RHN for updates. When running the migration scripts the command to enable the rhel-6-server-optional-rpms errors with "rhel-6-server-optional-rpms does not match a valid repository." Looking at the previous command (yum search subscription-manager-migration -v) after the line 'Updating Subscription Management Repositories" is says Unable to read consumer identity. I have a current RH license and the system is registered in RHN. What am I missing?
Yum Search command output:
Loading "rhnplugin" plugin
Loading "product-id" plugin
Loading "search-disabled-repos" plugin
Loading "security" plugin
Loading "subscription-manager" plugin
Updating Subscription Management repositories.
Unable to read consumer identity
