The issue about future versions is that you probably won't be able to import a keyring file directly. At the moment, a keyring file and the exported keyring format happen to be the same, but this is likely to change. A method that should work equally well today and in the future is:
gpg --export-secret-keys > my-secret-keyring.gpg
gpg --export-options export-local-sigs --export > my-public-keyring.gpg
(copy the files over)
gpg --import my-secret-keyring.gpg
gpg --import-options import-local-sigs my-public-keyring.gpg
It's an export plus an import, but you don't need to explicitly state which key(s) you want to play with. Just bring the whole ring over.
