You can install a license before, on or after its start date.
When you install a license, the license key is decrypted and then validated. Initially, the license state is set to pending. If the expiration date has passed, the state changes to expired. If the expiration date is in the future and the start date has passed, the license is activated and it's state changes to active. If the start date is in the future, the license state remains pending until the start date and is then activated on the start date.
From the left navigation menu, select Support and then License.
On the License page, click Create License.
Copy the license key to the clipboard and paste it into the License Key field.
The license is added.
Run the license add command.
