Can i separate CUCM cluster into different clusters
i have an existing cluster of four servers (MCS 7845, version 7.1.3) and i have two MCS 7845 not configured (new). i want to break my existing cluster into two clusters (2 servers each) and have the new servers on a separate cluster.
Is this possible? what do i need to do?
note that i have licenses on the existing cluster (UWL of professional, standard and entry)
Re: Can i separate CUCM cluster into different clusters
Sure you can. The server itself (hardware-wise) is not tied to a "cluster". You can remove 2 nodes from your 4 nodes cluster (System > Server > Delete) and make on of those a new Publisher, and the other a new subscriber. Then you can take the other 2 servers you haven't used at all and build another cluster.
Start building your clusters by installing Callmanager from scratch on each node. During installation the wizard will ask you if you want that particular server to be the primary node (publisher) or a secondary node (subscriber). Also, at some point you will be prompted to input a Security Password. This specific password needs to match on publisher and on subscribers within the same cluster.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
