I've been using a GPG key for awhile (mostly with the
pass password manager but also some with mail). Since it's now in use, a few years old, and entering the passphrase is getting tiresome, I thought I'd update/upgrade it with a new key and a shiny new Yubikey.
was quite helpful, but didn't mention how to handle data encrypted with the previous key(s). Is decrypting old data is going to require me to enter the passphrase to my old keys? If so, is there any way to replace the passphrase-encryption with encryption using my new key (that's stored on my yubikey)?
