Generate and add new encryption subkey?

Question

My encryption subkey (but not my signing or other subkeys) expired. How do I generate and add a new encryption subkey using gpg?

Are you sure you want to generate a new subkey and not extend the key's expiration date? — Michael Altfield, Jul 02 '20 at 15:26
@MichaelAltfield : good question. What's the best strategy between both options ? I asked the question (https://security.stackexchange.com/questions/274364/pgp-expired-encryption-subkey-renew-or-replace) — ChennyStar, Jan 29 '24 at 17:28
