Before You Begin: Important Update and Compatibility Notes

Before you begin the update process for Version 5.3.0.5, you should familiarize 

yourself with the behavior of the system during and after the update process, as 

well as with any compatibility issues or required pre- or post-update configuration 

changes.

Sourcefire strongly recommends you perform the update in a 

maintenance window or at a time when the interruption will have the least impact 

on your deployment.

For more information, see the following sections:

Configuration and Event Backup Guidelines

Before you begin the update, Sourcefire strongly recommends that you back up 

current event and configuration data to an external location. This data is not 

backed up as part of the update process.
Use the Defense Center to back up event and configuration data for itself and the 

devices it manages. For more information on the backup and restore feature, see 

the Sourcefire 3D System User Guide.

The Defense Center purges locally stored backups from previous 

updates. To retain archived backups, store the backups externally.
