Installing the Update
Before you begin the update, you must thoroughly read and understand these release notes, especially 
 and 
.
For minimum Firepower System version requirements, see 
. To update your appliances, see the guidelines and procedures outlined below:
Caution: 
Do not reboot or shut down your appliances during the update until you see the login prompt. The system 
may appear inactive during the pre-checks portion of the update; this is expected behavior and does not require 
you to reboot or shut down your appliances.
Note: 
Version 6.0 of the Firepower requires more memory than the previous versions for some Firepower Management 
Center models (previously referred to as the FireSIGHT Management Center or the Defense Center). To be specific, 
MC750 requires two 4GB dual in-line memory modules (DIMM). Similarly, MC1500 with 6GB of memory also requires 
additional memory. For more information see 
 and the Firepower Management Center Installation Guide.
When to Perform the Update
Because the update process may affect traffic inspection, traffic flow, and link state, Cisco 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.
Installation Method
You 
must
 install the FireSIGHT System Version 6.0.0 Pre-Installation package prior to updating the Version 6.0. For more 
information, see the 
Use the Firepower Management Center’s web interface to perform the update. Update the Firepower Management 
Center first, then use it to update the devices it manages.
Order of Installation
Update your Firepower Management Centers before updating the devices they manage.
Caution: 
URL category determination can introduce up to two seconds of delay in packet delivery, depending on 
local network conditions. If such delay is not acceptable, URL retry should not be allowed. Note that without URL 
retry, URL filtering may not be effective until such time as URL category and reputation determination completes for 
each URL. Until that time, packets that would have been filtered based on the URL’s category or reputation will be 
filtered based on the Uncategorized category. For more information on preventing URL retry, se
