3850 Stack Software Upgrade

[TF.DE]

Hi,

our WS-C3850-12XS Stack is running on SW Version 16.6.4a.

What's the recommended software version at the moment?

Is there an upgrade path to a version?

Are they special "How Tos" to upgrade the stack from software version A to version B?

Regards

Hi, can we go direct from 16.6.4.a to Version 16.12.07 or to any 3.6/3.7 Version?

If you want a stable firmware, upgrade to the latest 3.6.X or 3.7.X.  
Any IOS-XE version 16.X.X is very high in maintenance.

NOTE:  I have about >80 x 3850 stacks and I know which stacks have an uptime of >4 years without spitting out a single Tracebacks and it ain't those on 16.X.X.
