Migrate gocryptfs

I’m backing up files encrypted in gocryptfs. How do I migrate these to a different computer? There’s a step beyond copying them to the encrypted directory. encfs had a directory config file that I would copy over. Is there something similar in gocryptfs?

Besides the encrypted directory “cipher” in this example, the files in listing, plus optional keyfiles

$ ls cipher
gocryptfs.conf gocryptfs.diriv ZSuIZVzYDy5-TbhWKY-ciA==
