Cisco 1120 upgrade question

[Richard Tapp]

I currently have an 1120 running in appliance mode on ver 9.16(1) and need to upgrade due to a vulnerabilty.

The current recommended version is 9.18.4.29 (June 2024), although I would be more tempted to go for 9.18.4.24 (May 2024)

I cant find any document which says if you should do incremental upgrades, does any one know if you need to ?

I assume the 'Upgrade a Standalone Unit from Your Local Computer Using ASDM' on this link is the easiest wasy to do a single standalone upgrade and that it will put the new software into a loction that I will be able to find it in. (I cant see the current software on disk0: )

@Richard Tapp you can upgrade directly from 9.16 to 9.18.x, without an interim upgrade. https://www.cisco.com/c/en/us/td/docs/security/asa/upgrade/asa-upgrade/planning.html#reference_jt1_mnq_3tb

Upgrading via ASDM is the simpliest method to upgrade and will upload the file to the correct location on the device.
