Overview

This guide provides information about migrating an on-premises deployment to the Cisco UCM Cloud using the Yarnlab Wrangler UCMC Tool. During a migration, Cisco deploys the Unified CM cluster, then an administrator at the partner configures it, replicating the on-premises source cluster/s and register the end-user devices to the UCM cloud post migration.

The Wrangler UCMC tool supports migration of CUCM and if required, the associated Unity Connection, version 10.5 and later (currently latest supported is 14.X)

Additionally, it supports single and multiple CUCM clusters into a single UCMC cluster.

The CUCM cluster Dialplan can be migrated using one of the following methods

• Clone

• Map

• Template

The Clone option will clone the existing dial plan to the target CUCM cluster as is (this option is not supported for Multi Cluster migration).

The Map option requires that a dialplan is manually configured on the target cluster prior to migration, existing dialplan objects then have to be mapped to the target dial plan objects.

In the Template option, Wrangler will deploy either a standardised CUCDM type dial plan or a standard Simplified Dial Plan to the target cluster, existing dial plan objects then have to be mapped to the target dial plan objects.
