ASA 5520 upgrade

[sina.naser]

Hi everyone

We have a pair of ASA5520 in our extranet block and for some bugs wanna upgrade it. (Version 8.2(1))

Unfortunately it's reached end of support date 2 yrs ago and I cant find suggested software for it and manual document for upgrade. it's full of nat and must be converted. 

Any help will be appreciated.

Tnx in advance

you can only do - need to jump to 8.4 and then to 9.1.   ( cisco side still has Code to download if you have CCO account)

here is the upgrade path :

Note: Moving from 8.2 to 8.4 lot of things change, and 9.1 Many changed make sure you make a note. or copy the config out of the box. things may break.

hi,

what CVE or vulnerabilities you're trying to patch?

there's an 8.2.5 interim code which you can upgrade and don't have to change the NAT structure.
