Rolling Back to a Previous TOS Version
CAUTION To make sure you understand the effects of a software rollback, read the release notes for the current software version and the software version you are rolling back to before performing the rollback operation.
A rollback operation reverts the currently running software version on your X family device to a previous working version. The device retains settings and configurations However, not all functionality may be available depending on the version of the TOS you roll back to. For details, refer to the release notes for that version of the software.
When you perform a rollback of the software, the Update page displays a set of status messages. See “System Update Status Messages” on page 303 for details.
Persistent Settings
When you perform an operating system rollback, your current configuration settings are preserved, but filter settings roll back to the settings that were in effect when the rollback version was archived. Any changes to filter setting made after your target rollback version are deactivated, including attack protection filter updates.
