ASA 5505 UPGRADE FIRMWARE

[JAYESH RAMAIYA]

Hi

I have a Cisco ASA 5505 firewall which is running version 72.4. I want to upgrade this to 83.4.

The ASA have 512MB of memory already installed. Can this be done directly from 72.4?

Regards

Jay

Hi,

You can upgrade it directly. However before you start you need to ensure that you understand the all the features that will change as a result of the upgrade, for example NAT.

See below a guide to upgrading the software

Yes 512Mb of memory will be sufficient:
