Sourcefire 3D System Release Notes

Uninstalling the Update

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

Uninstalling the Update and Online Help

Uninstalling the Version 5.2.0.3 update does not revert the online help to its

previous version. If the version of your online help does not match that of your

Sourcefire 3D System, your online help may contain documentation for

unavailable features and may have problems with context sensitivity and link

functionality.

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.
