How can I transfer references from Reference Manager to EndNote?

Solution:

Export the references from the Reference Manager in e.g. RIS format, and then choose to import them into the EndNote library. (If you want them to have their own library, you can of course just import them into an empty library.)

Also see how to go from Reference Manager to EndNote if you want to switch programs and not just copy references from one to the other.
