Introduction to ciscocm.preUpgradeCheck-00022.cop.sgn Software
ciscocm.preUpgradeCheck-00022.cop.sgn is Cisco’s latest pre-upgrade validation utility for Unified Communications Manager (CUCM) and IM & Presence Server (IMPS) environments. Released in Q2 2025 under Cisco TAC advisory CSCwi93421, this COP file automates critical system health checks before upgrading to CUCM 14.0(1) or later. Designed for enterprises managing multi-node clusters, it identifies configuration conflicts, resource bottlenecks, and security vulnerabilities that could disrupt upgrade processes.
The tool supports:
- CUCM versions 11.5(1)SU8 through 14.0(1)
- IMPS clusters integrated with Webex Edge for Microsoft Teams
- Virtualized deployments on VMware ESXi 7.0 U3+ and Cisco UCS C220 M6 servers
Its SHA-512 signed package (build 00022) includes enhanced validation logic for hybrid cloud environments, aligning with Cisco’s 2025 Collaboration Suite interoperability standards.
Key Features and Improvements
1. Automated System Diagnostics
- Storage Validation: Scans for insufficient logging partition space (minimum 20GB required for CUCM 14.0 upgrades)
- Backup Integrity Checks: Verifies DRS backup completion status and consistency using SHA-256 hashing
- Security Posture Analysis: Flags TLS 1.0/1.1 ciphersuites and unpatched CVEs listed in Cisco Security Bulletin cisco-sa-cucm-2025-zyx987
2. Enhanced Protocol Compliance
- Validates SIP trunk configurations against 3GPP TS 24.229 v17.1 standards
- Detects non-compliant H.323 gateways lacking Cisco TIP certification
3. Performance Benchmarking
- Measures CPU/RAM utilization against CUCM 14.0’s 64-core/128GB baseline requirements
- Predicts upgrade downtime using historical cluster performance data
4. Cross-Platform Validation
- Supports Cisco UCS C-Series servers with 4th Gen Intel Xeon Scalable CPUs
- Verifies VMware vSphere 8.0 compatibility for virtual CUCM deployments
Compatibility and Requirements
| Category | Supported Specifications |
|---|---|
| CUCM Versions | 11.5(1)SU8+, 12.5(1), 14.0(1) |
| Server Hardware | UCS C220 M6, C240 M6; VMware ESXi 7.0 U3+ |
| Storage | RAID-10 with 500GB+ free disk space |
| Security | Cisco ISE 3.3+ for zero-trust policy validation |
Critical Notes:
- Incompatible with CUCM clusters using third-party LDAP directories without Cisco Secure Connect validation
- Requires Cisco Prime Collaboration 14.0 for historical performance trend analysis
Limitations and Restrictions
- Legacy System Exclusion: Does not support CUCM 10.x or IMPS 10.x environments
- Cloud Hybrid Scenarios: Limited validation for AWS Outposts deployments (requires manual checks via Cisco Cloud Insights)
- Certificate Validation: Cannot detect expired intermediate CA certificates in multi-tier PKI hierarchies
