Use this page to execute a customization XML file that has been previously saved on your system. Customization files provide a convenient way to modify your environment during deployment, from development to staging, from staging to production, or during design time.
You must be in a session to execute a customization file.
If you limit customizations to only resources modified in the current session, the Apply To column gets updated with the resources modified in current session. If you limit customizations of a project or folder, then the resources modified in current session within that project or folder are displayed in Apply To column.
To view customization details, within the session, select View Changes under Change Center, and click the Customization task. See Viewing Configuration Changes.
