1. Select references in a folder and choose Export
2. save as a RIS format
3. Create a new folder and drag and drop the RIS output file into a new folder or new Mendeley account
This will not transfer the full-text documents/pdfs, only the metadata [title, author(s) etc.]. You will have to download the document and then drag and drop those PDF(s) into a new Mendeley account. You can drag and drop PDF(s) from one folder to another.
