Image downgrade is not restricted, but is done at your own risk. Image Manager does not validate
downgrade cases.
Device Configurations supported by Image Manager
In addition to supporting image updates on standalone ASA devices, Image Manager manages the
filesystem and supports seamless image update for ASA devices specially configured for high
availability and scalability. Following configurations are supported:
•Multiple context mode—ASA in multiple context mode where a single ASA can be partitioned into
multiple virtual devices/firewalls. Refer to
http://www.cisco.com/en/US/docs/security/asa/asa91/configuration/general/ha_contexts.html.
Each of these virtual firewalls are represented in CSM as independent devices. When Image
Manager updates the image on the physical unit hosting these virtual devices, it updates device
properties of all virtual devices with the new image information.
