Merging two different secret keys is not currently supported. There
is a workaroung using "gpgsplit" (comes with GnuPG).
1) Export both secret keys into files
gpg --export-secret-keys 86ECAC0B > first.gpg
gpg --export-secret-keys --secret-keyring secold.gpg 490CC343 > second.gpg
2) Run gpgsplit on the second file.
gpgsplit second.gpg
3) Delete the parts you don't want. You only want the subkeys, so
delete everything until the first secret subkey packet (i.e. if the
first secret subkey is 000004, then delete 000001, 000002, and
000003).
4) Merge the keys:
cat first.gpg 00000* > newkey.gpg
5) Delete the current secret key
gpg --delete-secret-key 86ECAC0B
6) Bring in the merged key:
gpg --import newkey.gpg
Obviously, make a backup first!
