If Kaspersky Security is installed in a configuration with a DAG, you only need to add one Security Server key for all servers of the entire DAG. You can add keys by connecting the Management Console to any server within the DAG.
If you create a DAG group from servers on which the application was already previously installed and activated, you must activate the application for this group. To do so, you need to add one Security Server key after adding the first server to the DAG group.
Prepare a key file prior to activating the application. If you have only an activation code for a trial or commercial license, you can generate a key file based on the activation code. To generate a key file based on an activation code, you can use the Kaspersky website at https://activation.kaspersky.com/.
To add a key:
This opens the Add license window.
A reserve key for a Security Server can be added only if the Security Server has an active key. Only a commercial license key can be added as a reserve key. A trial license key cannot be added as a reserve key.
The key will be added, and its information will appear in the section corresponding to the key type.
