I need to upgrade Cisco IOS Software [Denali] version 16.3.6 to 16.3.7 on WS-C3850-24XS.
Can I know the required time in advance? It takes time to upgrade the HW image by Front-end Microcode IMG MGR...
Thank you for your cooperation in advance.

The execution of this command will take approximately 20 to 30 minutes. This command will only PUSH the firmware to all the stack members.
Because you're going from 16.3 to another 16.3 a microcode upgrade is not going to happen.
Reboot of the stack will be around 6 to 7 minutes.

Follow below prceedure.
Depends on how many switches in the stack, as per my experience, it was took 10-15min to reboot and come in to live and ready to use.
