want to remove punlisher and make subscriber as a Publisher
You can promote a subscriber, by installing the CallManager software again on the subscriber and choosing the option "I am upgrading/installing the CallManager Publisher " Your database will remain intact and the server will be upgraded to a publisher
Re: want to remove punlisher and make subscriber as a Publisher
As Niket noted above, there is no current method for "promoting" a Subscriber to a Publisher...at least not in the sense that you may be hoping for. Can you give us some background on what you are trying to accomplish by attempting to remove the Publisher and consolidate the cluster to 3 nodes? There are quite possibly a number of other considerations here depending on how services are running across the different nodes in the cluster.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
