You have created a new filesystem in `/new.enc` and mounted it to `/new`. The `df -Th` output would look like this: + +``` +$ df -Th +Filesystem Type Size Used Avail Use% Mounted on +[...] +/new.enc fuse.gocryptfs 30G 23G 5,7G 80% /new +/old.enc fuse.gocryptfs 30G 23G 5,7G 80% /old +``` + +Now you can simply use your graphical file manager to copy the files (or see the next sections for using command-line tools). + +Once you feel confident that have remembered the new passphrase (if you picked a new one) AND have stored the new masterkey at a safe place (this one is definitely new), delete `old.enc`. + +#### Using rsync + +I recommend using rsync because it allows to resume interrupted copies and is generally a lot smarter than anything else. + +``` +$ shopt -s dotglob +$ rsync -av /old/* /new +``` + +The bash option `dotglob` makes sure that `/old/*` also matches hidden files (dotfiles).
