I'm currently running 6.0(4)E1 and when I attempt to upgrade it says "Cannot upgrade software on the sensor. This package cannot be installed on the SSM-IPS10 platform."
I've tried upgrading via IDM, FTP, SCP and I get the same error.
I'm attempting to upgrade using the IPS-AIM-K9-6.1-1-E1 package.
Simple problem of using the wrong 6.1(1)E1 file.
The IPS-AIM-K9-6.1-1-E1.pkg file is specific to the AIM-IPS module for the ISR Routers.
The AIM-IPS module for the ISR Routers should not be confused with the ASA-AIP-SSM modules for the ASA appliances.
All other platforms (including the SSMs) should be using the standard 6.1(1)E1 upgrade file:
