2.4. Looking at Channel and Certificate Mappings

The subscription-manager-migration-data package contains a mapping file that maps RHN Classic channels to Customer Portal Subscription Management product certificates. This file (/usr/share/rhsm/product/RHEL-5/channel-cert-mapping.txt) uses simple keys to map the values:
channel_name: product_name-hash-product_cert.pem
For example, this maps the Red Hat Enterprise Linux Client channel to the corresponding product certificate:
rhel-i386-client-workstation-5: Client-Workstation-i386-b0d4c042-6e31-45a9-bd94-ff0b82e43b1a-71.pem
During migration, that mapping is translated into product_cert.pem and the product certificate is installed in the /etc/pki/product directory. For the rhel-i386-client-workstation-5, this migrates to the 71.pem product certificate (the last two digits of the mapping).
However, many channels are available for legacy systems only or have not yet released a product certificate. In that case, the channel has no mapping.
jbappplatform-4.3.0-fp-i386-server-5-rpm: none
This can create a situation where not all channels are migrated over to Customer Portal Subscription Management or where products are not fully subscribed.
