This section describes how to install the ASDM and operating system (OS) images.

We recommend that you upgrade the ASDM image before the OS image. ASDM is backward 
compatible, so you can upgrade the OS using the new ASDM; however you cannot use an old ASDM 
image with a new OS.

If the adaptive security appliance is running version 8.0 or later, then you can upgrade to the latest 
version of ASDM (and disconnect and reconnect to start running it) before upgrading the OS.

If the adaptive security appliance is running a version earlier than 8.0, then use the already installed 
version of ASDM to upgrade both the OS and ASDM to the latest versions, and then reload.
