The nxos.9.3.8.bin file is more than just a firmware update; it is a unified image that simplifies the deployment process across diverse hardware, including the Nexus 9300 and 9500 platforms.
Compatibility check is done. The switch will be reloaded to proceed with the upgrade. Proceed with upgrade? (y/n) [n] y nxos938bin hot download
