Chapter 1 Managing Feature Licenses
Configuring Licenses
Step 5 If you have additional Product Authorization Keys, repeat Step 4 for each Product Authorization Key.
After you enter all of the Product Authorization Keys, the final activation key provided includes all of
the permanent features you registered.
Activating or Deactivating Keys
This section describes how to enter a new activation key, and how to activate and deactivate time-based
keys.
Prerequisites
• If you are already in multiple context mode, enter the activation key in the system execution space.
• Some permanent licenses require you to reload the ASA after you activate them. Table 1-19 lists the
licenses that require reloading.
Limitations and Restrictions
Your activation key remains compatible if you upgrade to the latest version from any previous version.
However, you might have issues if you want to maintain downgrade capability:
• Downgrading to Version 8.1 or earlier—After you upgrade, if you activate additional feature
licenses that were introduced before 8.2, then the activation key continues to be compatible with
earlier versions if you downgrade. However if you activate feature licenses that were introduced in
8.2 or later, then the activation key is not backwards compatible. If you have an incompatible license
key, then see the following guidelines:
– If you previously entered an activation key in an earlier version, then the ASA uses that key
(without any of the new licenses you activated in Version 8.2 or later).
– If you have a new system and do not have an earlier activation key, then you need to request a
new activation key compatible with the earlier version.
• Downgrading to Version 8.2 or earlier—Version 8.3 introduced more robust time-based key usage
as well as failover license changes:
– If you have more than one time-based activation key active, when you downgrade, only the most
recently activated time-based key can be active. Any other keys are made inactive.
– If you have mismatched licenses on a failover pair, then downgrading will disable failover. Even
if the keys are matching, the license used will no longer be a combined license.
