Use the Compare Perspective and the Merge Perspective in a View Compare/Merge session (View Compare/Merge session) to compare or merge the contents of a source and target view, and to review or change the proposed merge actions for resolving item differences.
The View Compare/Merge Wizard uses the configuration to which the view is currently set to determine which choices to present on the first page of the wizard.
Optionally, uncheck the Start With Merge Perspective Current checkbox option on the Set Options page of the wizard if you want to start the session in the Compare Perspective.
This option is set to Start With Merge Perspective Current by default which causes the View Compare/Merge session to open in the Merge Perspective.
Select any other options you want and click Next.
