I'd like to update my ws-c3850-12xs from version 16.06.07 to 16.12.8. Do I need to follow an update path of different versions or can I simply upgrade to 16.12.8?

Direct upgrade to 16.12.8 can be done, however, I strongly recommend upgrading to the latest 16.6.X and avoid 16.9.X and 16.12.X altogether.

No you do not need to follow the upgrade path, you can do direct upgrade to the latest release Gibraltar- 16.12.7
Use the below upgrade link

Thanks for the tip. I will install the latest 16.6.X. I looked at install commands on the switch. The command software install is not recognized. I am able to enter the command software auto-upgrade source url flash:cat3k_caa-universalk9.16.06.09.SPA.bin but doesn't seem to do any thing nor does it return any errors.

The command is wrong. Please read the link I've provided.

Fantastic write up. Thank you. I'm now on version 16.6.9. Now I'll wait and see if my network issues have been resolved.
The following commands before rebooting the switch stack did not display any output.
more flash-1:packages.conf | begin for NOVA
more flash-2:packages.conf | begin for NOVA

more flash-1:packages.conf
more flash-2:packages.conf
Then use the following commands. For consistency purposes, the developers have changed the behaviour of each release.

I need to ask why avoid 16.9.X and 16.12.X altogether? It looks like several version sof 16.6.X fixed DHCP related issues, what I'm having trouble with. https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3850/software/release/16-6/release_notes/ol-16-6-3850.html#pgfId-1511816

16.9.X and 16.12.X introduces a feature called Cisco Smart License. A number of the background process for CSL are known (present tense) to cause CPU hogs and memory leaks.
Particularly 16.12.X there are numerous bugs found in 16.12.3 that the developers are unable to fix.
Also, read this: FN - 72323 - Cisco IOS XE Software: QuoVadis Root CA 2 Decommission Might Affect Smart Licensing, Smart Call Home, and Other Functionality and do Workaround 2.
