In my network I'm having 1 Publisher and 3 Subscribers. Now I want to remove Publisher Permanently and form all three Subscribers I want to activate 1 Subscriber as a Publisher in running Network.
Is this possible??
How can I do this??
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
......Before that have a backup....
The option of Publisher Resiliency is not on the roadmap and is not supported i.e. promoting a subscriber as a publisher.
take a backup
Reinstall the publisher
Populate the values of subscribers in system--> server
here is the checklist
Hope this helps

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.
