Uninstalling the Update

their synchronization. If you need to uninstall an update from redundant 

appliances, plan to perform the uninstallations in immediate succession.
To ensure continuity of operations, uninstall the update from clustered devices 

and paired Defense Centers one at a time. First, uninstall the update from the 

secondary appliance. Wait until the uninstallation process completes, then 

immediately uninstall the update from the primary appliance.

If the uninstallation process on a clustered device or paired Defense 

Center fails, do not restart the uninstall or change configurations on its peer. 

Instead, contact Support.

Uninstalling the Update from Stacked Devices

All devices in a stack must run the same version of the Sourcefire 3D System. 

Uninstalling the update from any of the stacked devices causes the devices in 

that stack to enter a limited, mixed-version state. 
To minimize impact on your deployment, Sourcefire recommends that you 

uninstall an update from stacked devices simultaneously. The stack resumes 

normal operation when the uninstallation completes on all devices in the stack.

Uninstalling the Update from Clustered Stacks

All devices in a clustered stack must run the same version of the Sourcefire 3D 

System. Uninstalling the update from any of the clustered, stacked devices 

causes the devices in that stack to enter a limited, mixed-version state. 
To minimize impact on your deployment, Sourcefire recommends that you 

uninstall the update from all devices in a stack simultaneously. First, uninstall the 

update from the devices in the secondary clustered stack. Wait until the 

uninstallation process completes, then immediately uninstall the update from the 
devices in the primary clustered stack.

Uninstalling the Update from Devices Deployed Inline

Managed devices do not perform traffic inspection, switching, routing, NAT, VPN, 

or related functions while the update is being uninstalled. Depending on how your 

devices are configured and deployed, the uninstallation process may also affect 

traffic flow and link state. For more information, see 

 on page 3.

After the Uninstallation

After you uninstall the update, there are several steps you should take to ensure 

that your deployment is performing properly. These include verifying that the 

uninstall succeeded and that all appliances in your deployment are 

communicating successfully.
