I am wanting to upgrade my software in my Cisco ASA 5505 before putting it into the production network. I have called Cisco to get some information about this but cannot seem to get a clear "yes you can" or "no you can't" upgrade answer so I thought I would post it here.
Here is what this device is currently running. (I just cut/pasted to prevent typos.)
So is this device upgradeable to any of the 8.4x versions? And if so, how do I go about obtaining a software upgrade? As said, the person I talked to at Cisco seemed as he couldn't answer my questions.
Between your software version and the newest one there are some major differences in the NAT format for example. Naturally if your current NAT configuration is simple it wont be that hard to convert to the new format.
Now to obtain the software I think you need to have a Smartnet contract with Cisco for this device to get support for this device through Cisco TAC and be able to download software through their site.
