Upgrading from Cisco Prime Infrastructure version 3.9 to 3.10 is a prudent decision for keeping abreast of the latest enhancements. While the idea of creating a snapshot of the existing Cisco Prime Infrastructure 3.9 for backup purposes is a common strategy, it's crucial to be aware of potential limitations. Snapshots primarily capture the VM's memory and disk state at a specific moment, designed for short-term use. Depending solely on a snapshot for a rollback may not account for database schema changes and configuration updates inherent in the upgrade process. Checking Cisco's official documentation and release notes for specific guidance is essential, as they may provide insights or cautions based on the nuances of the release. If feasible, testing the upgrade in a lab environment beforehand can help identify and address potential issues. Additionally, complementing the snapshot with a comprehensive backup of the Cisco Prime Infrastructure database and configuration is advisable. Establishing a well-documented rollback plan, scheduling the upgrade during a maintenance window, and ensuring access to Cisco support resources contribute to a more secure and informed upgrade process. Always consider the unique characteristics of your Cisco Prime Infrastructure deployment for a seamless transition and consult Cisco's documentation for the most accurate guidance.
