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.
yes it is possible, just make sure to make a backup up current PUB and restore on new HW, the old PUB will require a reinstall in order to work as a SUB.
just make sure to ask for a license rehost before this to have it before the actual process takes place
if this helps, please rate
