The document discusses maintaining a wireless LAN controller including upgrading the controller platform and code version, applying configuration changes, and backing up and restoring the controller configuration and Cisco WCS database. Key steps include checking the controller and AP inventory, upgrading controller code through the GUI which requires a reboot, uploading and downloading configuration files which can be encrypted, backing up the configuration to a TFTP server or manually from the CLI, and automatically backing up the Cisco WCS database when installing new versions.
