Can anyone tell me all the files that I need to upgrade my IDS from 6.0(5)E3 to 6.0(6)E4? I believe I should be able to do this with the hardware I currently have. I don't have the resources to upgrade the router or NM-CIDS module. I want to update to the E4 because it appears Cisco is no longer putting out signatures for the E3. From the documentation I'm reading I will need at least the System Image, the Service Pack, the Recovery Image, and the Engine Update files. I see several different file times that have AIM in the naming convention. I'm uncertain what specific file names I will need.
A show version capture is below.
