About the Restore Process
About the Restore Process
The ISO image you use to restore an appliance depends on when Cisco introduced support for that appliance
model. Unless the ISO image was released with a minor version to accommodate a new appliance model, ISO
images are usually associated with major versions of the system software (for example, 6.1 or 6.2). To avoid
installing an incompatible version of the system, we recommend that you always use the most recent ISO
image available for your appliance. For your convenience, you can install system software and intrusion rule
updates as part of the restore process. Keep in mind that only management centers require rule updates.
Management Centers use an internal flash drive to boot the appliance so you can run the restore utility.
We also recommend that you always run the latest version of the system software supported by your appliance.
After you restore an appliance to the latest supported major version, you should update its system software,
intrusion rules, and Vulnerability Database (VDB). For more information, see the release notes for the update
you want to apply, as well as the
version.
