CAUTION: On a SuperMassive™ 9800, you might need to update the ChassisOS and FailSafe versions
prior to installing SonicOS 6.2.1.3, 6.2.1.4, 6.2.7.7, or higher. You can view the ChassisOS and FailSafe
versions in SafeMode. See the SonicOS 6.2.1.x or 6.2.7.7 Release Notes for required versions. Please
contact SonicWall Technical Support before upgrading your SuperMassive 9800 appliance if these
versions are out of date.
NOTE: Starting in SonicOS 6.2.5.0, all SonicOS default certificates are updated to 2048‐bit/SHA‐256
encryption, except the Default SonicWall DPI‐SSL CA certificate which is updated starting in SonicOS
6.2.5.1. After upgrading your appliance to 6.2.5 or higher, do one or both of the following to replace the
older 1024‐bit certificates with the new ones:
• Navigate to the System > Administration page, scroll down to Web Management Settings, and click
the Regenerate certificate button. This regenerates the self‐signed HTTPS management certificate.
• Navigate to the System > Settings page, click Export Settings to save a copy of your configuration
settings, and then click the Boot icon for Current Firmware with Factory Default Settings. This will
regenerate all default certificates. After the restart, click the Import Settings button to import your
settings and return to your previous configuration.
