You upgrade the Flash Accel Management Console by deploying a new FMC virtual appliance. The virtual appliance contains any upgrade packages for the
Flash Accel Host and Guest OS Agents, as well as the software for the FMC. If you don't need to upgrade the FMC, and only want to upgrade the software for an agent, you can import the agent upgrade package to the virtual appliance from an ISO file.
If you don't need to upgrade the Flash Accel Management Console, and only want to upgrade a Host or Guest OS Agent, you can import the agent upgrade package to the FMC virtual appliance from an ISO file. Once you have updated the FMC with the new package, you can install the agent software on the target hosts or VMs.
