I am trying to degrade Ex460-G2 from 21.1.3.7 to 15.6.3.1. but this is error after loading firmware 15.6.3.1. it shows '15.6.3.1 does not contain a compatible flash memory driver'
I am going to upgrade on BlackDiamond 8800 from 15.6.4.2 to 16.2.3. Is it possible to performing a hitless upgrade. if not, what is the best step to upgrade it. Thanks in advance!
