vEdge devices don't support full downgrades. While reverting to the original version may succeed, attempting to downgrade to other versions often fails due to configuration database incompatibilities
-
Configuration Backup:
Always back up device configurations before version changes
-
Testing Environment:
Conduct thorough testing in non-production environments first
-
Release Notes:
Review target version release notes for new features and known issues
Interface and Module Compatibility
Beyond device models and software versions, interface and module compatibility significantly impacts SD-WAN deployments. Each device family has specific requirements for compatible interfaces and modules that must be considered during planning and implementation.
Conclusion
Device compatibility forms the foundation of successful Cisco Catalyst SD-WAN deployments. By carefully selecting appropriate device models and software versions while following best practices, organizations can ensure smooth implementations that fully leverage SD-WAN advantages.
