Red Hat Subscription Management for Self-Registered Satellite Upgrade
So I learned today while preparing to upgrade my Red Hat Satellite server from 6.2 to 6.3 before taking the next step in the path to 6.4, that self-registered Satellite server upgrade is not possible. This means I needed to unregister my server, basically from itself, and register it to the Red Hat CDN.
This process was not that big of a deal, until I realized that my Satellite Subscriptions were all already entitled to the Satellite manifest. There was a NOTE in the Red Hat docs that even provided a link to Managing Subscriptions, and you can look for yourself, but I didn't see any clear instructions on how to remove a subscription from the manifest.
