Updating Your Appliances
If you encounter issues with the progress of your update, contact Support. 
 
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.
Order of Installation
Update your Defense Centers before updating the devices they manage.
Installing the Update on Clustered Devices
When you install an update on clustered devices, the system performs the 
update on the devices one at a time. When the update starts, the system first 
applies it to the secondary device, which goes into maintenance mode until any 
necessary processes restart and the device is processing traffic again. The
