# Troubleshoot licenses that are shown as retained

There are several possible solutions when the State of a license is shown as “retained” in the Management Client.

##

Licenses can be generated based on the Management Server's proof-of-license (POL) code, the appliance’s proof-of-serial (POS) code, or a fixed IP address. When you start using a Management Server POL-based license, you bind it to the correct component, and the binding is fixed when you install the component's policy. Because of this fixed binding, if you unbind a Management Server POL-based license, it is shown as “Retained.” In this case, it is not possible to reuse the Management Server POL-based license on another component, or delete the Management Server POL-based license.

You can resolve issues with licenses shown as "retained" in the following ways:

- You can rebind the license to the component it was previously bound to.
- You can replace the Management Server POL-based license with a new Management Server POL-based license.
- You can replace the Management Server POL-based license with a new IP-address-bound license or POS-bound license.
- You can delete the element to which the Management Server POL-based license is bound. After the element is deleted, the state of the Management Server POL-based license changes to Unassigned and it can be rebound to some other component or deleted.
