We are planning to upgrade our CSM 4.2 SP1 to the latest version: 4.4 SP2. I was wondering has anyone done this before so I can get some Do's and Don’ts and also if someone can point me to the right documentation (step-by-step preferably) since I have not done this before and I don't know where to start from?
The devices that we are primarily managing via current CSM 4.2 SP1 are 2 x redundant ASA 5520 v8.2(3). After we successfully upgraded to CSM 4.4 we would like to upgrade the ASA unites to latest version 9.1
Any help will be very much appreciated.
