GPG: Change email for key in PGP key servers

From http://pgp.mit.edu/faq.html:

You cannot delete keys nor modify UIDs for keys uploaded to PGP key servers.

To change your email, you must add a new UID.

$ gpg --edit-key <keyID>
gpg> adduid
Real name: <name>
Email address: <email>
Comment: <comment>
Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? o
You need a passphrase to unlock the secret key for
user: "foo <foo@bar.com>"

Update the trust level of the new UID.

gpg> uid <new uid number>
gpg> trust
Your decision? 5
Do you really want to set this key to ultimate trust? (y/N) y
gpg> uid <new uid number>

Revoke the old UID.

gpg> uid <old uid number>
gpg> revuid
Really revoke this user ID? (y/N) y
Your decision? 4
Enter an optional description; end it with an empty line: <description>
Is this okay? (y/N) y

Save the changes. Upload the updated key to your PGP key server.

gpg> save
$ gpg --keyserver hkp://pgp.mit.edu --send-keys <keyID>
