3.3. Removing a subscription from a system using the command line

In some scenarios, you may need to remove a subscription from a system; you may be upgrading the system which requires a new subscription or trying to free an entitlement for another system.
To remove a system, use the command:
[root@server1 ~]# subscription-manager remove --poolnumber

Note

You can also remove all subscriptions from the system using
subscription-manager remove --all
