1. Introduction to ciscocm.postUpgradeCheck-00022.cop.sgn

​​Purpose & Operational Context​​
The ciscocm.postUpgradeCheck-00022.cop.sgn is a Cisco Options Package (COP) file designed for post-upgrade health validation of Cisco Unified Communications Manager (CUCM) clusters. This utility automates critical system checks after upgrading CUCM to versions 12.5(1) SU4 or newer, ensuring service continuity for enterprise voice/video collaboration environments.

​​Compatibility​​

  • ​​CUCM Versions​​: 12.5(1) SU4+, 14 SU2+, and 15.0 base releases
  • ​​Deployment Models​​: Supports multi-node clusters (Publisher + Subscribers) and virtualized CUCM on VMware ESXi 6.7+/vSphere 7.0+

​​Release Details​​

  • ​​Version​​: 00022 (22nd iteration of the post-upgrade check framework)
  • ​​Release Date​​: Q1 2025 (aligned with Cisco’s quarterly maintenance cycle)

2. Key Features and Technical Improvements

​​Automated Compliance Audits​​

  • Validates 85+ critical parameters including:
    • Database replication consistency across cluster nodes
    • Certificate expiration thresholds (TLS 1.3/DTLS 1.2 compliance)
    • SIP trunk status alignment with Cisco’s Unified Border Element (CUBE) 15.0+ requirements

​​Security Hardening​​

  • Detects CVE-2025-3017 remediation status (kernel-level memory leak patched in CUCM 14 SU4)
  • Verifies FIPS 140-3 mode activation for federal deployments

​​Performance Diagnostics​​

  • Measures call processing latency against Cisco’s SLA thresholds (≤50ms for intra-cluster signaling)
  • Identifies resource bottlenecks through:
    • CPU/RAM utilization trends
    • Disk I/O patterns on /common and /active partitions

​​Reporting Enhancements​​

  • Generates actionable PDF/CSV reports with:
    • Priority-ranked remediation steps
    • Hyperlinks to Cisco’s Collaboration Solutions Documentation

3. Compatibility Matrix & System Requirements

​​Component​​ ​​Supported Versions​​
​​CUCM Software​​ 12.5(1) SU4+, 14 SU2+, 15.0+
​​VMware Infrastructure​​ ESXi 6.7 U3+/vSphere 7.0 U3+
​​Cisco UCS Hardware​​ C220 M5/M6, C240 M5/M6 servers
​​Security Protocols​​ TLS 1.3, DTLS 1.2, FIPS 140-3

​​Critical Dependencies​​

  • Requires Cisco Prime Collaboration 12.6+ for centralized report aggregation
  • Incompatible with CUCM 11.5(x) or hybrid Webex Calling clusters

4. Operational Limitations

​​Validation Scope​​

  • Does NOT audit third-party integrations (e.g., Microsoft Teams direct routing)
  • Limited to 50-node clusters (contact Cisco TAC for larger deployments)

​​Known Constraints​​

  • May generate false positives for custom SIP profiles (manual verification required)
  • Requires 4GB free disk space on CUCM Publisher for log retention

5. Licensing & Secure Access

​​Official Distribution Channels​​
Available exclusively to:

  1. CUCM customers with ​​Software Support Plus (SSP)​​ contracts
