Presently running ASA 5510 CSC SSM with the Trend Micro Interscan. Updates are failing apparently due to changes made by TrendMicro. So far looks like only option is to upgrade version from 6.3.1172.0 to version 6.6.1125.0.
My ASA presently has 256mb ram and 256mb compactflash. It is my understanding that that is not sufficient memory for upgrade. Do I need to upgrade both the dram and the compactflash, is it pretty much just swapping out the modules, will it need to be reconfigured?
