Hi Udaya,
Thanks for writing to us.
On this page:
https://docs.appdynamics.com/display/PRO45/Metrics+and+Graphs#MetricsandGraphs-CompareReleasesTool
There is a section that reads:
Compare Releases Tool
The compare releases tool lets you view the "before and after" effects on performance from the changes you make in your application environment. It puts the performance data from two timeframes side by side, so that you can easily compare performance differences.
To use the tool:
In the left navigation pane of the Controller UI, under More, select Compare Releases.
Set the time ranges to compare from the Time Range drop-down menus in both panes.
Select the entities to compare in the Select What to Compare panel.
Select the metrics that you want to compare from the View drop-down menu.
Click Compare.
Compare Releases
Let me know if this helped you.
Thanks,
Megha
