upgrade cisco asa 7.2 to asa 8.x

Hi all,

I would like to upgrade the asa version of my cisco asa 5510 from 7.2 to 8.x(latest version). Will this upgrade be smooth? Do i need to check to see if my entire configuration stay the same after upgrade? Anything to look for during this upgrade? Pls advise. Thks in advance.

Re: upgrade cisco asa 7.2 to asa 8.x

Hi Don,

It depends on what you mean by "8.x (latest version)". If you mean 8.3, the configuration will be significantly different. If you mean the latest 8.0 or 8.2 build, things will be fairly similar but you'll still want to check the release notes for new features, open caveats, and configuration changes. Here are the ASA release notes:

Hope that helps.

Re: upgrade cisco asa 7.2 to asa 8.x

I went from 7.0.4 to 8.22 without any issues whatsoever.

Do you have a failover set of ASA's?  If so, you can use the zero-downtime upgrade.  After you've upgraded one of them let it become the primary and if there are major issues fail back to the other while you roll back the upgrade.

As stated above, 8.3 is a whole different story as it changes the way NAT is configured.

Hello,

As others have mentioned, there are significant changes with NAT and ACL on ASA software version 8.3.  Here is the migration document which details these changes:

Hi all,

THk you very much for the details. I will review before doing the upgrade.

By the way the reason why i wanted to do the upgrade is because only asa8.x supports netflow.

Cheers!!
