upgrade 3850 to 3.3.3 or 3.6.0

I'm currently running 3.3.1. In the 3.3.3 release notes I see there's a resolved bug which I've been struggling with for a while so I want to upgrade.

In researching what other issues I might run into, I found bug CSCuo85722 where the 3850 stops forwarding traffic and the details say 3.3.3 appears to be affected (but no mention of 3.3.1 or 3.6.0)

I know every environment is different but can anyone give me an idea as to whether I should be going to 3.3.3 and taking my chances or try going right to 3.6.0 (unless 3.6 is a problematic release. I think I saw a bug or forum post where going from 3.3.2 to 3.6 was in a stack didn't work properly causing constant reloads or something and user had to go back )

Hi CrackedJack1,  Safe Harbor

Hi CrackedJack1, 


Safe Harbor's option for 3850 platform is 03.03.03SE release, which would be a good option to upgrade if you're looking for stability. 03.06.00E introduced more supported features.


As for CSCuo85722, based on the information of this bug this has been mark as a duplicate issue for CSCui59593 which description indicates that it does not affect 03.03.03SE.


Hope that this information is helpful!
