Are you recommending...

$ gpg --armor --export-options export-local-sigs --export >pub.asc

instead of

$ gpg --armor --export > pub.asc

and

$ gpg --import-options import-local-sigs --import pub.asc

instead of

$ gpg --import < pub.asc

?

Or should
$ gpg --import-options import-local-sigs --import pub.asc
$ gpg --armor --export-options export-local-sigs --export >pub.asc
$ gpg --import-options import-local-sigs --import pub.asc
$ gpg --import < pub.asc
all be done?


And this all functions with gpg2 in place of gpg ?

Please note that  while I greatly appreciate that Mr. Hansen wrote a
program to handle this, I still like having the option of doing things
manually.

Thanks!

Welcome!  And your question is not trivial.

The following is the procedure I use on UNIX systems:

First, export all public certificates into a public keyring:

	$ gpg --armor --export > pub.asc

Second, export all secret certificates into a secret keyring:

	$ gpg --armor --export-secret-keys > priv.asc

Third, export ownertrust values and save those:

	$ gpg --armor --export-ownertrust > trust.asc

Fourth, copy all the *.conf files in ~/.gnupg into your current director
y:

	$ cp ~/.gnupg/*.conf .

Fifth,  put these, and all your GnuPG .conf files, all into a single
archive:

	$ tar cJf gpg-backup.txz pub.asc priv.asc trust.asc *.conf

Copy gpg-backup.txz to the new machine.  Once you've done that,
uncompress it on the new machine:

	$ tar xJf gpg-backup.txz

Import your secret certificates:

	$ gpg --import < priv.asc

Import your public certificates:

	$ gpg --import < pub.asc

Import your ownertrust values:

	$ gpg --import-ownertrust < trust.asc

Make sure your ~/.gnupg directory exists.  If it doesn't, run gpg with
no arguments and hit Ctrl-C to break out of it.

	$ gpg

Copy your .conf files into ~/.gnupg:

	$ cp *.conf ~/.gnupg

... And at that point you should be done.  This technique should work
regardless of whether you're migrating from 1.4 to 2.0, 1.4 to 2.1,
2.0 to 1.4, 2.0 to 2.1, 2.1 to 2.0, or 2.1 to 1.4.  No matter which
you're doing, you're covered.

It's a good idea to not copy the random_seed file.  PRNG states should
not be shared between computers.

Follow the above process and they will be.  Your private certificates
were exported, as were the trust assignments.

See the above process.

None.
