Contact technical support in order to delete the old licensed device and free up the license. Before you contact support, please have the following information ready:
If the Security Analytics appliance was previously licensed and you are trying to license the appliance with a different license key, you must first completely delete all remnants of the old key on the appliance. This requires CLI access as root from an SSH session. DO NOT perform these steps if your license key has not changed. Performing these steps with the same license key that was used previously will consume an additional license in the system.
