In this example we will be upgrading Firepower Management Center virtual appliance (formerly known as Firesight) from version 6.0.1.3 to 6.1.0-33.  This process needs to take place before the Firepower sensors are upgraded.

 

Pre-Reqs

Ensure you have backups of the FMC. As its virtual I’d also recommend taking a snapshot as well.

 

Check the upgrade path on the Cisco website

 

 

Run in the pre-installation (optional but recommended) package

 

Ref: 

 

Download the pre-installation package (Sourcefire_3D_Defense_Center_S3_Pre-install-6.0.1.999-1252.sh) from Cisco website.

Upload the update to the FMC:   

System -> Updates -> Product Updates -> Upload Update -> {Browse download} -> Upload

 

 

Ensure all devices are communicating correctly and there are no running tasks

System -> Health -> Monitor

 

Install Pre-Install package

System -> Updates -> {Install Icon}

Note: No reboot is required.

 

 

Upload upgrade package & run readiness check

Download update (in this case: Sourcefire_3D_Defense_Center_S3_Upgrade-6.1.0-330.sh )  from Cisco website then upload to the appliance. (like in steps above)

SSH to appliance and run following commands:

Syntax:

sudo install_update.pl --readiness-check /var/sf/updates/{filename}

Command to run in our example:

sudo install_update.pl --readiness-check /var/sf/updates/Sourcefire_3D_Defense_Center_S3_Upgrade-6.1.0-330.sh

 

(you will be prompted for password}

 

 

Monitor progress and confirm process completes successfully.

 

Upgrade FMC

Click the install icon:

 

 

Confirm install

 

You can see the status of the install :

Eventually you will be logged out. If you decide to log back in you can see the status of the update:

Finally the appliance will reboot:

 

You should then be able to connect back into your appliance and check the status of the update.
