[alberto-pesce]

Hi all,

 I would update my ASA 5505 from 

Cisco Adaptive Security Appliance Software Version 8.2(1)

Device Manager Version 6.2(1)

to 

Cisco Adaptive Security Appliance Software Version 8.4(2)

Device Manager Version 6.4(5)

Do you  think is needed to change something in the configuration or the firmware update do not impact on the running-configuration ?

Let me know, if you had some experience on that.

Best Regards an Thanks in advance

ASA 8.2 to 8.4 code change, you need to Look NAT and configuration.

Make sure you have backup of the config, and do upgrade understand maintenance window, and roll back plan in place, incase upgrade fails.
