Download the software from the hosting server.

Performing system sanity check...

You are running firmware download with 'fullinstall' option.
This command will preserve startup-config file and license file across firmware download and auto-replay configs
This command will cause a cold/disruptive reboot and will require that existing telnet, 
secure telnet or SSH sessions be restarted.

Do you want to continue? [y/n]:

Log back into the device.
The fullinstall option retains the startup configuration file. Upon the automatic reboot of the device, the startup configuration file is reloaded automatically.

Verify the new software version.

Both partitions on the device or on the modules should contain the new software.
