Sourcefire 3D System Release Notes

Uninstalling the Update

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

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.
The next sections include detailed instructions not only on performing the update,

but also on completing any post-update steps. Make sure you complete all of the

listed tasks.

Uninstalling the Update from a Managed Device

The following procedure explains how to use the local web interface to uninstall

the Version 5.2.0.5 update from managed devices. You cannot use a Defense

Center to uninstall the update from a managed device.
Uninstalling the Version 5.2.0.5 update results in a device running Version 5.2.0.5.

For information on uninstalling a previous version, refer to the release notes for

that version.
All managed devices reboot when uninstalling the Version 5.2.0.5 update.

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

or related functions during the update. Depending on how your devices are

configured and deployed, the update process may also affect traffic flow and link

state. For more information, see
