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.
...
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.

Migration Process
The migration process goes through a number of steps as per below pictures
...
Prerequisites
Recommendations for using the Wrangler UCMC Tool
...
Minimum Mapped Objects (need to be configured on target system)
MRGL (MRG)
CMG
Data Extraction
Configuration is extracted from the source and target clusters and imported into Migration Assistant including all lines, devices, users and dial plan
Configuration can be periodically rediscovered if required for phased migrations
