Replace a Single Server or Cluster

Replace a Single Server or Cluster

This document describes how to replace a single server or an entire cluster for Cisco Unified Communications Manager Release 8.6(1). Replacement means that you replace the server hardware while preserving the server configuration. The replacement server operates identically to the old server.


Because this process is designed to work as a server replacement, you need to do it in the live environment. Cisco does not recommend doing this process on a "dead net" because a duplication of the entire network environment is required, which is highly risky.
