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¶
- Log in as provider, reseller, or customer administrator, depending on the hierarchy level where the CUP cluster was configured.
- 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.
- Choose Device Management > CUP (deprecated) > Migrate CUP to CUCM Cluster.
- From the From CUP Cluster drop-down menu, choose the CUP cluster you want to migrate.
- From the To CUCM Cluster drop-down menu, choose the Unified CM cluster to which you want to migrate the CUP cluster.
- 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.
