License deactivation removes an activated license. You can deactivate a purchased license to make it available for activation on another machine. Deactivation also applies if replacement of the machine's operating system or hardware changes the system ID and invalidates the license. The license cannot be reactivated (reused) until you complete all the deactivation steps.
If the software license you want to deactivate is on a machine that is not connected to the Internet, use the offline deactivation method available in the License Portal.
In the Deactivate tab you can start a new offline deactivation or complete an in-progress deactivation.
Use an online deactivation if the machine where the license is installed has an Internet connection. Refer to Software Manager Help (LIT-12012389) for information on how to use the online deactivation method.
