Hi
I have two Cisco 9500-40X-E switches with StackWise Virtual setup. They are running with Cisco IOS XE Fuji 16.9.3 image.
Can I upgrade the images to IOS XE Gibraltar 16.12.2 directly? I have found the following steps from the Cisco website, but I want to confirm whether it will work fine as I am going to update the firmware remotely in production environment. (These steps doesn't show copying the new firmware from tftp server to the switch)
