Introduction to ciscocm.cuc_preUpgradeCheck-004.cop.sgn
This cryptographically signed COP file serves as Cisco’s official pre-upgrade validation toolkit for Unified Communications Manager (CUCM) and IM & Presence Service (IMPS) environments. Released on August 29, 2024 (version 004), it automates 38 critical system checks required before upgrading CUCM clusters to versions 12.5(1) and later.
The “.sgn” extension confirms Cisco’s digital signature verification, ensuring code integrity from download to deployment. System administrators use this tool to prevent upgrade failures in enterprise voice/video collaboration environments supporting 500+ endpoints.
Key Features and Improvements
1. Comprehensive System Diagnostics
- Validates partition space allocation against CUCM 12.5’s 25GB minimum requirement
- Checks database replication status across cluster nodes
- Verifies TLS 1.2 compliance for third-party integration endpoints
2. Enhanced Security Protocols
- Adds FIPS 140-3 compliance checks for secure media processing
- Detects deprecated SHA-1 certificates requiring replacement
3. Operational Efficiency Tools
- Generates HTML report with categorized warnings (critical/high/medium)
- Identifies inactive device accounts consuming license allocations
4. New Validation Capabilities
- Checks compatibility with Cisco Expressway X14.2 integration
- Verifies VMware ESXi 8.0 U3 hypervisor configurations
