You do not have to actively transfer a license, but rather, this is done automatically in the background. If, when installing F-Secure Internet Security, you have used up all your available licenses, the software detects that your subscription has reached its maximum number of installations (used licenses) and reassigns the licenses as follows:
The licenses available with your subscription are released from your devices.
The new installation is assigned the first available license on your subscription.
Your other devices with Internet Security installed get reassigned the licenses available.
Note: If you have installed Internet Security on more devices than there are licenses available with your subscription, the last device to connect to the servers does not obtain a license. You can then uninstall Internet Security from this computer.
