Well, folders are easy because you just copy the folders using the method I included in my last post. If you have the paid version, you can also write tags and ratings to JPG files so they will travel with the images when you transfer. See this for more information on how we handle metadata: http://www.fstopapp.com/metadata/
For albums, there is an menu option in the albums view to backup your albums. For smart albums this works very well since it is based on conditions. For regular albums we must include the path for the files so the folder structure must be the same on the new device for them to transfer correctly.
Let me know if that helps.
