Uninstalling the Update
Uninstalling the Update from Devices Deployed Inline
Managed devices do not perform traffic inspection, switching, routing, 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 from Sourcefire Software for X-Series
You must uninstall the update from each VAP group individually in order to fully 
uninstall the update from Sourcefire Software for X-Series. Uninstalling the 
Version 5.3.0.2 update of the Sourcefire 3D System reloads the affected VAP. If 
your Sourcefire Software for X-Series is deployed inline and you are using 
multi-member VAP groups, Sourcefire recommends that after you uninstall the 
update from a VAP, you allow that VAP to reload before you uninstall the update 
from additional VAPs.
This allows the other VAPs in the group to inspect network traffic while the 
affected VAP reloads. If you are using single-VAP VAP groups in an inline 
deployment, reloading the VAP causes an interruption in network traffic. Make 
sure you plan the uninstallation for a maintenance window or other time when it 
will have the least impact on your deployment.
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 5.3.0.2 update from managed devices. You cannot use a Defense 
Center to uninstall the update from a virtual managed device.
Uninstalling the Version 5.3.0.2 update results in a device running Version 5.3. For 
information on uninstalling a previous version, refer to the release notes for that 
version.
Uninstalling the Version 5.3.0.2 update reboots the device. Managed devices do 
not perform traffic inspection, switching, routing, 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
