Using Rufus to create bootable USB Drives for Cisco ISE 3495 upgrade

[ajc]

I will give a try in the lab but I just wanted to know if somebody else tried this option before.

You should give it a try, it should work. Generally we use iso-to-usb.sh script  to create it.

Firstable I have to said that I received a brand new 3495 Cisco ISE with version 1.3.0.876 already installed on it BUT my deployment is running 1.2.1.198 patch 3 so I had to downgrade that box.

Hi Saurav, using Rufus did NOT work. I got an installation error so I found that using DAEMON TOOL Lite (trial version), I created a virtual DVD drive on my Win 7 Laptop which pointed to the ISO for version 1.2.1.198. Then I could make the downgrade with no issues. This is a Cisco Appliance not VM.

I think the procedure indicated by cisco in the following link is INCOMPLETE:

I will post some additional screenshots required on that link when you are using CIMC and upgrading/downgrading the ISE using External/Virtual DVD.

Important to say that I found this mechanism using Virtual DVD the easiest one instead of the bootable flash drive.
