[Nishad Ismail]

We are planning to change the cucm cluster mode to mixed mode ,Please suggest

Cucm Version 11.x

The mixed mode is mandatory for the cisco Expressway ?

any risk while changing the Non-secure mode to mixed mode ..?

utils ctl set-cluster mixed-mode  

              &

CUCM cluster reboot will do the job ?

No, mixed mode is not mandatory for expressway, I'll assume you mean MRA here

Read the security guide for all the info about this
