Upgrade the Virtual Controller
In the early steps of installation, the Cisco Virtual Controller initially required an OVA file for new virtual appliance creation. However, maintaining virtual controller features and software upgrades require a common AES file downloadable from the Cisco website.
Complete these steps:
1. Download the AS*7_3*aes file to a target host (for example, the TFTP/FTP server).
2.Just as for legacy controllers, go to the web GUI of the controller > COMMANDS > Download File. Select the File Type, Transfer Mode, IP Address, File Path, and File Name (.aes file). Click Download in order to start the process.
3.When the process has completed successfully, you are prompted to Reboot in order for the new software image to take effect. Click the link to the Reboot Page in order to continue.
