If you have purchased a new license, use the Recovery Manager Console to update the license key file.
In the Recovery Manager Console, right-click the Recovery Manager for Active Directory console tree root, and then click About.
In the About dialog box, click the License tab, and then click Install License File.
In the Update License dialog box, enter the path and name of the license key file, and then click OK.
When the actual number of user accounts exceeds the licensed number, Recovery Manager for Active Directory returns a warning message each time you back up data. In this case, you can revoke licenses from the domains whose backups you no longer need. The revoked licenses are returned to the pool of available licenses and you can allocate them to a different domain.
When you revoke licenses from a domain, all backups created by Recovery Manager for Active Directory for that domain get deleted. You should only revoke licenses from a domain if you no longer need backups created for that domain.
In the console tree, right-click the root node, and then click About.
In the About dialog box, click the License tab.
On the License tab, select the domain from the License Usage list, and then click Revoke.
In the confirmation message box, click Yes.
