Also, you must use FTP to transfer your uploaded images to the new location.
Please do a test-run first if you are SQL-savvy. If you encounter any errors, save the message output you get - it will definitely help debugging!
This is NOT an importer meant for upgrading Serendipity. This importer assumes that both Serendipity installations use the same version.';
