We have had our 2 x ASA 5520's for a couple of years now. They work in active/passive failover mode and run IOS 8.2(2). I would like to upgrade to the latest version 8.3, but it seems I need my memory to be 2GB, is it possible to upgrade to this?
It is quite cheap to upgrade my 2 ASA's, is it easy to do? I guess I could upgrade the standby unit first then flip it over to be the active ASA then upgrade the other. I've never opened up an ASA before
