Just copy the folder from one to the other. Don't worry about the separate encryptions being different, that is just a randomization of the keys (Salt or UniqueIV) to make cracking harder. I use unison to synchronise the encrypted files of a encfs file-systems between three systems, no problems. Others I know do the same via a DropBox. What I would recommend is using some system that keeps the .encfs6.xml separated from encrypted files. Transfer it separately to machines that are 'allowed' to access the encrypted data. Now while this file only contains public parts of the encryption, why give that file to 'crackers'? Without it it becomes even harder to 'crack' an encryption. I treat it a bit like a 'second key'. I not only need my pass phrase, But I also need that file, to access my encrypted filesystem. Look at the encfs environment variable ENCFS6_CONFIG Unfortunately may of the encfs apps doesn't let you separate the config from the encrypted data.
