Introduction to ciscocm.preUpgradeCheck-00043.cop.sha512

This Cisco Options Package (COP) file serves as an automated diagnostic tool for validating Unified Communications Manager (CUCM) clusters prior to major version upgrades. Released under Cisco Collaboration Flex Plan 3.2 in Q1 2025, the “00043” revision (version 14.0.1-43) introduces enhanced compatibility checks for hybrid cloud deployments and multi-cluster environments.

The tool systematically evaluates 38 critical system parameters including database consistency, certificate expiration timelines, and hardware resource thresholds. Administrators deploying CUCM 14.0(1)SU4 or later must complete these checks before initiating upgrades to prevent service interruptions.

Key Features and Improvements

  1. ​​Comprehensive System Diagnostics​​

    • Validates TLS 1.3 cipher suite compatibility across cluster nodes
    • Detects expired PLM/SMARTS licenses with 90-day expiration warnings
    • Verifies free disk space against CUCM 14.x minimum requirements (50GB+ for /common partition)

  2. ​​Security Validation Framework​​

    • SHA-512 checksum enforcement prevents tampered file execution
    • Identifies vulnerable TLS certificates scheduled for FIPS 140-3 compliance
    • Cross-references CVE-2025-xxxx advisories with installed software versions

  3. ​​Operational Efficiency Enhancements​​

    • 60% faster scan completion (avg. 8.2 mins vs legacy 13.5 mins)
    • JSON report generation for integration with Cisco Prime Infrastructure
    • Automated backup validation with 256-bit AES encryption checks

  4. ​​Cloud Readiness Assessments​​

    • Validates AWS/Azure instance types against Cisco Hybrid Cloud Matrix
    • Checks inter-cluster latency thresholds for Webex Calling integrations
    • Verifies DNS SRV record configurations for cloud DNS providers

Compatibility and Requirements

Supported Platforms

Component Minimum Version Notes
CUCM Publisher Node 11.5(1)SU3 Mandatory for diagnostic execution
IM&P Server 12.5(1)SU2 Presence service compatibility checks

​​Release Date​​
January 15, 2025 (Included in CUCM 14.0(1)SU4 bundle)

Limitations and Restrictions

  1. ​​Diagnostic Scope​​

    • Does not validate third-party CRM integrations (e.g., Salesforce CTI)
    • Limited support for CUCM clusters with mixed 12.x/14.x nodes

  2. ​​Operational Constraints​​

    • Requires cluster-wide service activation window for full diagnostics
    • Incompatible with CUCM Express deployments
