Updating Your Appliances

Configuration and Event Backup Guidelines

Before you begin the update, Sourcefire strongly recommends that you back up 

current event and configuration data to an external location. This data is not 

backed up as part of the update process.
You can use the Defense Center to back up event and configuration data for itself 

and the devices it manages. For more information on the backup and restore 

feature, see the Sourcefire 3D System User Guide.

When to Perform the Update

Because the update process may affect traffic inspection, traffic flow, and link 

state, Sourcefire strongly recommends you perform the update in a 

maintenance window or at a time when the interruption will have the least impact 

on your deployment.

Installation Method

Use the Defense Center’s web interface to perform the update. Update the 

Defense Center first, then use it to update the devices it manages.
Although you can install a managed device update from its local web interface, 

Sourcefire strongly recommends using the Defense Center, especially for older or 

less powerful managed device models.

Order of Installation

Update your Defense Centers before you update the devices they manage.

Installing the Update on Paired Defense Centers

When you begin to update one Defense Center in a high availability pair, the other 

Defense Center in the pair becomes the primary, if it is not already. In addition, 

the paired Defense Centers stop sharing configuration information; paired
