Introduction to ciscocm.preUpgradeCheck-00019.cop.sgn

This COP (Cisco Options Package) file serves as an automated diagnostic toolkit for Cisco Unified Communications Manager (CUCM) environments preparing for version upgrades. Designed per Cisco’s UCM 11.5(1) upgrade guidelines, it performs 32 critical pre-flight checks to validate system readiness, including:

  • Disk space allocation (minimum 40GB free in /common partition)
  • Database schema consistency
  • Active security advisories requiring remediation
  • Service redundancy status

Compatible with CUCM clusters running 9.x to 12.5(1) and IM & Presence Service (IMPS) 10.0(1) and later. The “-00019” suffix indicates the 19th iteration of this validation framework, incorporating updated compatibility checks for TLS 1.2 enforcement and IPv6 dual-stack configurations.

Key Technical Enhancements

​​1. Multi-Node Cluster Validation​​
Simultaneously audits publisher and up to 8 subscriber nodes for:

  • NTP synchronization drift (<50ms tolerance)
  • Certificate expiration thresholds (flags CSCsb38211 if <30 days)
  • Cross-version TFTP file consistency

​​2. Security Posture Analysis​​
Integrated CVE cross-referencing against:

  • PSIRT advisories for SQL injection risks (CSCwd72984)
  • Outdated third-party libraries (OpenSSL <3.0.8)
  • Unpatched XSS vulnerabilities in Cisco Prime Collaboration

​​3. Upgrade Path Compliance​​

  • Blocks upgrades attempting to skip intermediate SU versions
  • Detects deprecated hardware (e.g., UCS C220 M3 servers)
  • Validates VMware ESXi 6.7 U3 or newer for virtual deployments

​​4. Diagnostic Reporting​​
Generates encrypted .tar.gz bundles containing:

  • Real-time service status (RTMT equivalent)
  • CDR/CMR database integrity hashes
  • Customizable retention period (7-90 days)

Compatibility Requirements

Component Supported Versions Notes
CUCM 9.1(2) to 12.5(1) Requires 8GB RAM per node
IMPS 10.0(1) to 12.5(1) Presence Gateway redundancy mandatory

​​Restrictions​​:

  • Incompatible with Expressway CE clusters
  • Requires disabled CDP/LLDP during validation
  • FIPS mode installations need separate FIPS-compliant COP
