Hi,
In my cluster I am having one cucm pub, one cucm subscriber and two uccx servers on UCS server (C210 M2) .
Now I need to upgrade the cucm from 8.5(1) to 8.5 (1)SU3.
And UCCX is also need to be upgraded from 8.5(1) SU1 to 8.5 (1)SU2 with COP file.
Please help me on the step by step upgradation procedure.
