i have a isr 4451-x router with fuji 16.9.2 which i need to upgrade to 16.9.3 , i read the upgrade manual which was very confusing and unclear so i was wondering is it just like the old method of doing the below
no boot system
then
boot system bootflash:isr4400-universalk9.16.09.03.SPA.bin
then reload? and the router would come up with the new image?
