WS-C3850-48XS iOS Stack Upgrade Install Mode

[Heinz]

Good Day,

I have searched for install / upgrade steps and found many, all different and some vague.

Found this: https://www.youtube.com/watch?v=bX006rPu4pA

Not sure but this looks like a safe bet?

Any feedback will be appreciated

Please refer to Cisco 3850: IOS-XE/Firmware Upgrade

And be careful of CSCvq53573.

Thank you,

My current version is: 16.3.8 and I intend to upgrade to 16.12.8

I see there is a lot of references to 3.X.X ?

Please read that page properly.  There are only two lines that mentions 3.X.X.
