Searching support for sunrise and domain mapping without dates impossible so I ask this again.

Reading the usage log in domain mapping plugin info it indicates 2 things are required. I just want to confirm this to be accurate.

1. move sunrise.php into wp-content
2. set define( 'SUNRISE', 'on' );

Are the above two items required with an activated domain mapping plugin?

What happens if define( 'SUNRISE', 'off' )? If deactivating domain mapping plugin should this be set to OFF??

Thank you.
