Upgrading Remotely

When you upgrade the wireless software remotely, the upgrade program upgrades the software image by using the image file that is located on an external FTP server. The upgrade program downloads the image file from the FTP server, unpacks it and installs it directly on the system without retaining a local copy of the image file. The Wireless Assistant GUI displays Remote as the upgrade option for upgrade from a remote FTP server with FTP selected as the protocol.

Note

SCP can only be used to download an image and cannot be used to start remote upgrade. The Upgrade now button is disabled when SCP is selected from the drop-down list.

Caution

You should always backup the existing software image during the upgrade process. Backing up provides you the option of restoring your controller to its previous configuration if needed. For more information, see Restoring the Backup Image from the GUI.
