Upgrade procedure (for this example we will be using the TFTP server)

  2. Make sure all firewalls are off
  3. Make sure that the TFTP server interface shows the correct IP address of the computer It is installed on

  1. Once the virtual controller is rebooted, the adopted APs should upgrade automatically. On some models the adopted APs will not automatically upgrade after the virtual controller has been upgraded and rebooted, in this case upgrade the virtual controller again by following steps 6 to 9. After the second virtual controller upgrade and reboot, the adopted APs should automatically upgrade. 
Additional notes
Upgrading the adopted APs from the virtual controller will not work if:
  • You are using local instead of remote upgrade
  • You are upgrading from CLI (Non-express units only)
  • You are using anything other than TFTP or FTP, i. e. HTTP
