Here's a link where you can find all Cisco Visio stencils/icons.
You can downgrade a Cisco 3850 or 3650 Catalyst switch from IOS-XE 16.x to 3.x. In this case, the Cisco 3850 runs a "newer" 16.6.2 software code.

You can use the "newer" way to upgrade or downgrade using the request platform software package install switch all file flash:<IOS-XE> new auto-copy privileged exec command. In this case I "downgrade" to the old IOS-XE 3.6.7 code.
Issue a reload command for the new code to take effect.
