I have an existing cluster of 2 CUCM server running 6.1(2). They are using MCS-7825-H3.
I will be adding a new MCS-7835 server which I intend to make this the Publisher instead due to its better performance and power redundancy.
Was wondering if its possible to replace the existing Pub with the new MCS-7835 server. The "downgraded" Pub will serve as a Subscriber node instead.
