It's time for our company to upgrade our Core switches (2x 6509 Sup720 in VSS).
My question is if we should care about choosing a IOS image which has the certification "Safe Harbor" or not since the newest IOS image for Sup720 with "Safe Harbor" is from 15-MAR-2014 (12.2.33-SXI13), which is quite old.
We are currently running 12.2.33-SXI7 which is rather old now.
What are your experiences with IOS stability when not choosing a "Safe Harbor" certified IOS for a VSS configuration?
We would prefer to jump right into the newest one available: 15.1.2-SY6, do anyone have any good or bad experience with this version in a VSS config that they could share?
