/mcpDescription Installation Method Note This installation method is applicable only for VMware vSphere ESXi. Fresh install, add nodes to, or direct migrate a cluster of Unified Communications Manager and IM and Presence Server using Cisco Prime Collaboration Deployment. See the Cisco Prime Collaboration Deployment Administration Guide for the following: • Fresh Install Task (where PCD performs similar operation as Touchless Install of a Single Node or Cluster). • Edit/Expand Task (where PCD performs similar operation as Touchless Install to add a single node). • Migration Task (where PCD is performing direct migration of an entire cluster). Use this method when: • You require assistance with multiple nodes of one cluster and/or multiple clusters, and a separate management application is acceptable. • (PCD Migration Task only) you are "repaving" an existing installation where you are dealing with one or more of the following: • Two or more of these factors as part of the same migration—site moves, hardware changes, VMware upgrades, application version upgrades, application readdresses, and in scenarios where more flexibility is expected than what direct upgrades can provide. • You need to rebuild, restore or recover a cluster, or you need to revert configuration changes. Here, you are looking for a more flexible approach than what Unified Communications Manager Disaster Recovery Solution can provide.
