Updating Your Appliances

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 

system then applies the update to the primary device, which follows the same 

process.

Installing the Update on Stacked Devices

When you install an update on stacked devices, the system performs the updates 

simultaneously. Each device resumes normal operation when the update 

completes. Note that:

If the primary device completes the update before all of the secondary 

devices, the stack operates in a limited, mixed-version state until all devices 

have completed the update. 

If the primary device completes the update after all of the secondary 

devices, the stack resumes normal operation when the update completes 

on the primary device.

Installing the Update on X-Series Devices

Note that if you uninstall a version of Cisco NGIPS for Blue Coat X-Series, you 

must restart the VAP before a new installation. This process can take several 

minutes.
To update to Version 5.3.0.6, Sourcefire Software for X-Series must be running at 

least Version 5.3.
You cannot update Sourcefire Software for X-Series running Version 4.10.x to 

Version 5.3.0.6. Instead, you must uninstall the previous version and then install 

Version 5.3 before updating to Version 5.3.0.6. For detailed instructions, see the 

Sourcefire Software for X-Series Installation and Configuration Guide.
