Updating Your Appliances

Order of Installation

Update your Defense Centers before updating the devices they manage.

Installing the Update on Paired Defense Centers

When you begin to update one Defense Center in a high availability pair, the other 

Defense Center in the pair becomes the primary, if it is not already. In addition, 

the paired Defense Centers stop sharing configuration information; paired 

Defense Centers do not receive software updates as part of the regular 

synchronization process.
To ensure continuity of operations, do not update paired Defense Centers at the 

same time. First, complete the update procedure for the secondary Defense 

Center, then update the primary Defense Center.

Installing the Update on Clustered Devices

When you install an update on clustered devices, the system performs the 

update on the devices one at a time. When the update starts, the system first 

applies it to the secondary device, which goes into maintenance mode until any 

necessary processes restart and the device is processing traffic again. The 

system then applies the update to the primary device, which follows the same 

process.

Installing the Update on Stacked Devices

When you install an update on stacked devices, the system performs the updates 

simultaneously. Each device resumes normal operation when the update 

completes. Note that:

If the primary device completes the update before all of the secondary 
devices, the stack operates in a limited, mixed-version state until all devices 

have completed the update. 

If the primary device completes the update after all of the secondary 

devices, the stack resumes normal operation when the update completes 

on the primary device.

Installing the Update on X-Series Devices

To update to Version 5.3.0.3, Sourcefire Software for X-Series must be running at 

least Version 5.3.
You cannot update Sourcefire Software for X-Series running Version 4.10.x to 

Version 5.3.0.3. Instead, you must uninstall the previous version and then install 

Version 5.3 before updating to Version 5.3.0.3. For detailed instructions, see the 

Sourcefire Software for X-Series Installation and Configuration Guide.
Updating the Sourcefire Software for X-Series reloads the affected VAPs. If your 

Sourcefire Software for X-Series is deployed inline and you are using 

multi-member VAP groups, Sourcefire recommends that you update the VAPs
