Introduction to ciscocm.postUpgradeCheck-00019.cop.sgn Software

Designed for Cisco Unified Communications Manager environments, ​​ciscocm.postUpgradeCheck-00019.cop.sgn​​ serves as a critical post-upgrade diagnostic tool to validate system integrity after software updates. This COP (Cisco Options Package) file performs automated checks on configuration consistency, service status, and hardware compatibility – a standardized practice observed in Cisco Collaboration solutions since 2023.

Compatible with ​​Cisco Unified Communications Manager 14SU2 and later versions​​, the tool supports virtualized deployments on UCS C-Series servers and HyperFlex hyperconverged infrastructure. The current iteration (build 00019) was released on April 30, 2025, addressing new upgrade validation requirements for mixed-mode clusters.

Key Features and Technical Improvements

Core Validation Capabilities:

  1. ​​Multi-Layer Configuration Audit​​

    • Cross-verifies database parameters with active service configurations
    • Detects residual settings from previous versions (e.g., deprecated TLS 1.0 protocols)

  2. ​​Cluster Health Monitoring​​

    • Validates node synchronization status in expanded clusters (up to 20 nodes)
    • Checks resource allocation consistency across subscriber servers

  3. ​​Security Compliance Checks​​

    • Identifies unpatched vulnerabilities from previous builds
    • Verifies FIPS 140-3 compliance status post-upgrade

Version-Specific Enhancements (Build 00019):

  • ​​Enhanced Diagnostics for Cisco ISDN Gateway Integration​​
    Resolves false positives in PRI gateway status reporting observed in build 00018
  • ​​Multi-Tenancy Support Verification​​
    Adds validation checks for partition resource allocation in Service Provider deployments
  • ​​Certificate Chain Validation​​
    Implements stricter checks for intermediate CA certificates during security updates

Compatibility and System Requirements

Supported Platforms Minimum Requirements Compatibility Notes
Cisco Unified CM 14SU2 16GB RAM
200GB storage		 Requires ESXi 7.0 U3 or later
Cisco Unity Connection 15 Red Hat Enterprise Linux 8.6 Limited validation for third-party storage arrays
Cisco IM&P Service 15 UCS C240 M6 servers Requires CUCM 14SU2 cluster pairing

​​Critical Compatibility Considerations​​:

  1. Hardware Security Module (HSM) integrations require firmware v3.2.5+
  2. Mixed Cisco Jabber client versions (12.9-14.0) may trigger false alerts
  3. Not validated for Expressway Series edge devices
