I have an issue upgrading the IDSM-2 module I'm playing with.
It is currently running version 5.0(2).
The thing is when I try to upgrade the image to the latest 6.x version using the .bin.gz file, I get the follwing error message :
The filename IPS-IDSM2-K9-sys-1.1-a-6.1-2-E3.bin.gz is not a valid upgrade file type.
Continue with upgrade? :
There is no image file that is not .bin.gz on the download section of the website. Only recovery images have the .pkg extension.
Does anybody how to troubleshoot this simple(I guess) upgrade issue?
