• Source prefix filters objects in the source bucket.
• Destination prefix is added to keys of all transferred objects.

For example, if the source prefix is test_dir/ and the destination prefix is migration/, the data transfer only works with source objects that have keys starting with test_dir/. In the destination, the data transfer replaces the test_dir/ prefix in object keys with migration/. A source object named test_dir/somefile.txt becomes migration/somefile.txt in the destination.
