Upgrade 8.4.1 to 8.4.5

[Bradford.berry]

Hello,

I am upgrading a active/standby pair of asas 5520's from 8.4.1 to 8.4.5. I am wondering if there is anything i need to be careful of. I do use a lot of Nat policys and i have had issues with 8.4.1 and proxy arp so i hard coded alot of my nat ip's.

is there a good procedure? I want toupgrade one and keep one shut down while i test all my applications and connectivity and then bring it back online and upgrade it.

Thanks,

Brad

There's no syntax change between those versions so you should be just fine.

Simply follow the recommended procedure for Zero Downtime Upgrade for an active/standby ASA pair.

I've done it dozens of times and it works perfectly.

arp permit-nonconnected

You're welcome.

They added that command as a new feature but it will not affect the configuration and syntax of your current 8.4(1) running-config when it migrates into a system running 8.4(5).

Features like that which are new (vs. changes to existing features' behavior) only become a factor after you've upgraded and the decide to start to use them. That's independent of the upgrade process.
