Actually I just remembered something, the process I originally described is only going to work going to from version 2.1 to the 2.1.0.64xx. In version 2.0 ryzom cfg and user files are stored in the containers folder of the Library, 2.1 uses application support folder.
So if using 2.0 upgrade to 2.1 first. Then replace the files in the application with new ones.
