Conduct thorough testing in a lab or non-production environment to simulate the upgrade process and identify any potential issues.

8. Health Check:

Perform a health check on your ACI fabric to identify and resolve any existing problems or inconsistencies before starting the upgrade.

9. Prepare Rollback Plan:

Have a well-defined rollback plan in case the upgrade encounters unforeseen issues. This plan should include step-by-step instructions to revert to the previous state.
