hi,

Re: ASA 5520 8.2 Failover

For ASA failover to form you must have both ASA boxes same RAM. In your case they won’t form the failover as RAM is different on both boxes.

 

 

here is the link.

Re: ASA 5520 8.2 Failover

Couple of things you need to note.:

 

You have old ASA code running which 8.2 ( suggest to upgrade to latest stable to get best out of performance)

if you decided to upgrade if you other box to test for your feature before you build ha.

 

if you still like to use same code for some reason, here is the guide for 8.2

 

https://www.cisco.com/c/en/us/td/docs/security/asa/asa82/configuration/guide/config/ha_active_standby.pdf

 

 basic rule of building HA  -  make sure HARDWARE / ASA  CODE exactly need to identical.
