Upgrade ASA Software from 8.3.2 to 8.4.3


does anybody did an Upgrade from an 8.3 version to the new version 8.4.3 and can give some hints or links to read?

I only have a production system and nothing to test and I don' want to get a nasty surprise...

Thanks a lot in advance

Upgrade ASA Software from 8.3.2 to 8.4.3

If you're already on 8.3(2) you've already gotten past the tricky bit - the new NAT syntax and access-list object use. There are some minor changes with identity NAT in going up to 8.4(3) as described here but that's about it as far as things to watch out for.

The TAC is quite helpful and it is a good idea to open a case proactively just to have them on hand to take a quick look at any issues that come up. The TAC security team deals with these upgrades every day and is very adept at zeroing in on the root cause of  any issues you are having and setting things straight within in few minutes.


Upgrade ASA Software from 8.3.2 to 8.4.3

I'm almost certain that the parts of the configruation that have changed (the additon of the "no-proxy-arp route-lookup") commands will be migrated over during the upgrade without issue.
