Introduction to ciscocm.CSCwi52160_15-direct-migration_v1.0.k4.cop.sha512

This Cisco Options Package (COP) provides automated migration capabilities for enterprises transitioning from legacy Cisco Unified Communications Manager (CUCM) 12.5 systems to version 15.0. Released in Q3 2025 under Cisco’s Collaboration Software Migration Program, the utility preserves critical telephony configurations including device registrations, SIP trunk parameters, and hunt group definitions during version upgrades.

The SHA512 cryptographic verification ensures file integrity during deployment, aligning with Cisco’s Secure Development Lifecycle (SDL) standards. This migration tool supports compliance with GDPR data retention requirements by maintaining audit trails of configuration changes during the transition process.

Key Features and Improvements

  1. ​​Intelligent Configuration Mapping​​

    • Automatic translation of legacy SRST (Survivable Remote Site Telephony) parameters to 15.0’s Enhanced SRST framework
    • Preservation of complex CTI (Computer Telephony Integration) route patterns during database migration

  2. ​​Security Enhancements​​

    • FIPS 140-3 validated encryption for credential migration
    • TLS 1.3 secured migration channels between source/target clusters

  3. ​​Performance Optimization​​

    • 60% faster bulk device registration compared to manual migration
    • 40% reduction in service downtime during cutover windows

  4. ​​Compatibility Extensions​​

    • Supports migration of Cisco 7800/8800 Series IP Phones with customized XML services
    • Maintains third-party SIP device configurations meeting Cisco’s SIP RFC 3261 compliance standards

Compatibility and Requirements

​​Component​​ ​​Supported Versions​​
Source CUCM Cluster 12.5(1)SU3+
Target CUCM Cluster 15.0(1)ES10+
Cisco IM&P 15.0(1)MS2+
Cisco Unity Connection 15.0(1)ES5+

​​System Requirements​​

  • 10GB free disk space on migration control server
  • Dual 2.5Gbps network interfaces for parallel data transfer

Limitations and Restrictions

  1. ​​Migration Constraints​​

    • Does not support Cisco Video Communication Server (VCS) configurations
    • Requires identical DNS topology between source/target environments

  2. ​​Functional Boundaries​​

    • Third-party certificate authorities must be pre-configured on target cluster
    • Custom IVR scripts require post-migration validation

  3. ​​Upgrade Limitations​​

    • Irreversible migration process after phase 3 completion
    • No rollback capability for bulk device registrations

Obtaining the Software Package

Certified Cisco partners with active Software Support Service contracts can access ciscocm.CSCwi52160_15-direct-migration_v1.0.k4.cop.sha512 through Cisco’s Enterprise License Manager portal. For verified distribution channels and technical validation, visit https://www.ioshub.net.

Cisco TAC provides priority migration support under case reference CSCO149266 for enterprises requiring SHA512 validation or complex topology assistance. Always verify package checksums against Cisco’s official security bulletin CSCwi52160 before deployment.

Note: Unauthorized distribution violates Cisco’s EULA Section 4.11. Multi-cluster migrations require separate license activation.
