The MARS upgrade packages are the primary vehicle for major, minor, and patch software releases. In addition to addressing high-priority caveats, upgrade packages update system inspection rules, event types, and provide the most recent signature support.
For detailed instructions on planning and performing an upgrade or installation, refer to “ Checklist for Upgrading the Appliance Software ” in the Cisco Security MARS Initial Configuration and Upgrade Guide .
To ensure that the upgrade from earlier releases is trouble free, this section contains the notes provided in previous releases according the release number. Please refer to the notes that pertain to the release you are upgrading from and any releases following that one.
- If you are upgrading from Windows 2003 to Windows 2008, ensure that any ancillary devices and software you employ are supported. For more information see Supported and Interoperable Devices and Software for Cisco Security MARS Local Controller 6.x.
- When downloading software packages from CCO to MARS, ensure that your credentials (username or password) do not include the ampersand (&) character. The credential will be truncated before being passed to the authentication module, which results in an error message about invalid user credentials.
- The MARS Appliance performs a file system consistency check (fsck) on all disks when either of the following conditions is met:
The fsck operation takes a long time to complete, which can result in significant unplanned downtime when rebooting the system after meeting a condition above. For example, a MARS 50 appliance can take up to 90 minutes to perform the operation.
The upgrade process to 6.0.1 differs based on the release you are upgrading from. If you are upgrading a 5.x release, you can upgrade to 6.0.1 if you are running 5.3.6. The upgrade from 5.3.6 to 6.0.1 takes several hours, as it also upgrades the Oracle database running on the appliance. If you are running an earlier 5.x release, you must first upgrade to 5.3.6 .
However, if you are upgrading a 4.x release, you must migrate the system instead of upgrading. To migrate from a 4.x, you must follow the step-by-step instructions specified in the Migrating Data from Cisco Security MARS 4.x to 6.0.1 .
Note When upgrading a “restricted” model of MARS appliance (20R, 100e, or GCm) to MARS Software release 6.0.1, all limits enforced by the restricted model are ignored. The “restricted” models perform as unrestricted models (20, 100, or GC) once upgraded to release 6.0.1.
When upgrading from one software release to another, a prerequisite release is always required. This prerequisite release is the minimum level required to be running on the appliance before you can upgrade to the most recent release. Table 1 identifies the upgrade path that you must follow to reach the minimum level required to upgrade to current release.
Migration required . See Migrating Data from Cisco Security MARS 4.x to 6.0.1
