Uninstalling the Update

Uninstalling the Update

The following sections help you uninstall the Version 5.3.0.6 update from your 

appliances:

Planning the Uninstallation

Before you uninstall the update, you must thoroughly read and understand the 

following sections.

Uninstallation Method

You must uninstall updates locally. You cannot use a Defense Center to uninstall 

the update from a managed device.
For all physical appliances, uninstall the update using the local web interface. 

Because virtual managed devices and Sourcefire Software for X-Series do not 

have a web interface, you must use the bash shell to uninstall the update.

Order of Uninstallation

Uninstall the update in the reverse order that you installed it. That is, first uninstall 

the update from managed devices, then from Defense Centers.

Uninstalling the Update from Clustered or Paired Appliances

Clustered devices in high availability pairs must run the same version of the 

Sourcefire 3D System. Although the uninstallation process triggers an automatic 

failover, appliances in mismatched pairs or clusters do not share configuration 

information, nor do they install or uninstall updates as part of 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 

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 fails, do not restart 

the uninstall or change configurations on its peer. Instead, contact Support.
