Migrate CUP to a Cisco Unified CM Cluster

Use this tool to migrate your CUP (also known as IM and Presence Service) nodes to a Cisco Unified Communications Manager cluster, which is the recommended configuration. Migrating CUP nodes to a Unified CM cluster is hierarchy-specific. A Customer CUP node can only be migrated to a Customer Unified CM cluster and not to a Provider or Reseller cluster. A Publisher IM_P node is added first, then Subscriber nodes.

When migrating your CUP to a Unified CM cluster, the following conditions apply:

  • Cluster versions must be the same for both the clusters.
  • The IPv4 address or hostname and domain configuration must not be duplicated within the cluster.
  • Two devices cannot have the same server name.
  • No more than one CUP publisher can be migrated to the same Unified CM cluster.
  • Multiple subscribers can be migrated to the same Unified CM cluster.

Procedure

  1. Log in as provider, reseller, or customer administrator, depending on the hierarchy level where the CUP cluster was configured.
  2. Set the hierarchy path to the hierarchy node where the CUP cluster was configured. For a shared configuration, this would be a provider or reseller node. For a dedicated configuration, this would be a customer node.
  3. Choose Device Management > CUP (deprecated) > Migrate CUP to CUCM Cluster.
  4. From the From CUP Cluster drop-down menu, choose the CUP cluster you want to migrate.
  5. From the To CUCM Cluster drop-down menu, choose the Unified CM cluster to which you want to migrate the CUP cluster.
  6. Click Save.

The migrated CUP server is removed from the list under Device Management > CUP > Servers and now appears under Device Management > CUCM > Servers as server type IM_P. The cluster name for the migrated servers is now the same as the Unified CM cluster name.
