Introduction to ciscocm.cuc_postUpgradeCheck-002.k4.cop.sha512

This SHA-512 validated COP file serves as Cisco’s standardized ​​Post-Upgrade Health Check Utility​​ for Unified Communications Manager (CUCM) clusters. Released on August 29, 2024, version 002.k4 automates post-migration verification for CUCM 11.5(1) and later environments, ensuring service continuity after major version upgrades.

Designed for Cisco Unified Communications Manager 14.x clusters and IM & Presence Service (IMPS) nodes, it performs 48 automated checks across database consistency, device registration status, and service health metrics. Compatible with virtualized CUCM deployments on UCS C220/C240 M6 servers running VMware ESXi 8.0 U2 or later.

Key Features and Improvements

  1. ​​Comprehensive System Auditing​​
  • Validates cluster-wide service synchronization (CTI, TFTP, Certificate Authority)
  • Detects orphaned device records in CDR Analysis & Reporting (CAR) databases
  1. ​​Security Enhancements​​
  • CVE-2024-6387 mitigation verification for SSH service hardening
  • TLS 1.2/1.3 protocol compliance checks for inter-node communications
  1. ​​Diagnostic Automation​​
  • Comparative analysis of pre-upgrade (PreUpgradeCheck) and post-upgrade states
  • Automated generation of Tech Support Archive (TSA) bundles for Cisco TAC
  1. ​​Performance Optimizations​​
  • 40% faster check execution compared to v002.k3 (avg. 18-minute runtime reduction)
  • Reduced memory footprint (max 512MB RAM utilization during scans)

Compatibility and Requirements

​​Component​​ ​​Supported Versions​​
CUCM 11.5(1) SU8 – 14.0(1)
IM & Presence Service 11.5(1) SU6 – 14.0(1)

Limitations and Restrictions

  1. ​​Upgrade Constraints​​
  • Incompatible with CUCM clusters using legacy Unity Connection 10.x integration
  • Disabled service checks for deprecated Jabber 11.x client configurations
  1. ​​Feature Restrictions​​
  • Limited diagnostic granularity for Cisco Expressway C/E systems (requires separate COP)
  • No support for multi-cluster reporting in CUCM 14.x Business Edition deployments
  1. ​​Known Issues​​
  • False positives in CAR database validation during peak call volumes (≤2% occurrence)
  • 90-second service startup delay false alerts in clusters with >50 nodes
