AdRotate Switch is not a migration tool between 2 AdRotate (pro) installations.
As the description states, AdRotate Switch allows you to import adverts and relevant stuff from other (3rd party) plugins into AdRotate (Pro).
If you want to copy adverts between 2 AdRotate setups you can use the export option in AdRotate (Pro) > Adverts, in the bulk actions.
Or you can export and import a sql dump in PHPMyAdmin with the relevant tables.
