We are currently running version 184.108.40.206 on our ACS appliances (the actual appliances, not a Windows or UNIX box). I would like to upgrade them to the lastes version, which is now 220.127.116.11 (although, since that is so new, I'd be happy with 18.104.22.168). However, I cannot find the base install for any of these versions, 4.2.0 or 4.1.4.
On the download site, it only has patches, not the full base image. Where can I get the full version upgrade?
