I will be upgrading a production CCM 5.11 to version 8.0. What is the requirements and the upgrade path? Please advise.
First of all , you have to go through the below link to check if your hardware need any upgrade to support 8.0
from the below link there is no direct upgrade from 5.11 to 8.0 , thus you need to upgade from 5.11 to 6.1(2) then from 6.1(2) to 8.0
Best Regards ,
