CISCO ASA 5505 UPGRADE PATH 9.1 SERIAL

Because a Cisco ASA device can have only one permanent activation key installed at any given time, every new key must encompass the entire set of desired features. You can enable additional features without a time limit by applying a different permanent activation key. Although the system does not require this key for basic operation, some advanced features, such as failover, depend on the permanent activation key in order to operate correctly. This is the permanent activation key, which never expires. Even though these core features do not require an explicit activation key, one usually comes installed anyway.

Permanent and Time-Based Activation KeysД®very Cisco ASA model comes with a certain set of basic features and capacities enabled by default the Base License permanently activates these features on the particular platform. All features encoded in a particular key always have the same licensed duration, so activation keys can be classified as permanent or time-based. You can request and apply another key with a different set of features to the same Cisco ASA device at any future point in time.

After Cisco generates a key for a given device, you cannot separate individual features from this licensed package. The complete set of activation keys resides in a hidden partition of the built-in flash device of a Cisco ASA other nonvolatile internal memory structures maintain a backup copy of that information.

Each activation key is only valid for the particular hardware platform with the specific encoded serial number. A series of five hexadecimal numbers, as shown at the top of the output in Example 3-1, typically represents that string.

Make the standby ASA active again, if required to maintain the original active ASA as active.An activation key is an encoded bit string that defines the list of features to enable, how long the key would stay valid upon activation, and the specific serial number of a Cisco ASA device.

Make the standby ASA the active firewall.

Make the Standby ASA the active firewall.

When it comes up, make the necessary changes to the NAT and ACLs with regards to object group usage.

upgrade the standby ASA version to 8.4 (boot system flash: ).

download 8.4 and 9.1 from website and copy both to the ASA's flash.

The 5520 requires 2GB of memory (upgrade memory if required)

check to see if the ASAs have the correct amount of memory.

So the steps would be something like this: You also need to make sure that the ASAs have the correct amount of memory to support 8.3 and higher software. The path I would recommend is to upgrade both units to 8.4 first and then to 9.1. I am uncertain what type of behavior you will see when when going to 9.1 as I have not had to upgrade to that version yet.ДЄlso, if i'm going from 8.2 to 8.4 to 9.1, am i going to have to first upgrade the standby to 8.4 reboot, then upgrade to 9.1, reboot? You will however se error messages stating that the versions are not the same. If the pair is broken, would I still be able to issue failover commands (failing active to standby, failing standby back to active,etc.?)ДЇrom my understanding, as long as you are within the 8.x release of the ASA software you will be able to issue failover commands and replicate config between the two devices.
