Uninstalling the Update

The following sections help you uninstall the Version 5.2.0.1 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 and virtual Defense Centers, uninstall the update using 

the local web interface. Because virtual managed devices do not have a web 

interface, you must use the 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 and Defense Centers 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.
