Application performance can be a subjective topic during and after a migration. Interpretation of performance profile and metrics will need to be definitively agreed upon prior to migration. This will allow all parties to reach consensus based on agreed upon metrics quickly.
Ensure identification and collection of proper KPI’s during planning. Proper KPI metrics should be monitored with enough time to provide adequate data for comparison of application performance before and after migration to minimize performance evaluation and narrow a scope of investigation if the application is not performing once migrated.
VMware Wavefront or VMware Aria Operations (SaaS) could be helpful in monitoring application KPI’s.
