+== Changing your PGP key ==
+
+If you are planning on migrating to a new PGP key and you also want to
+change your key in LDAP, you need to create a ticket in
+[[trac||https://trac.torproject.org/projects/tor/newticket]] in the
+{{{Tor Sysadmin Team}}} component:
+* The ticket should include your username, your old PGP fingerprint
+  and your new PGP fingerprint.
+* The ticket should be PGP signed with your PGP key that is currently
+  stored in LDAP.
+
+=== Revoked or lost old key ===
+
+If you already revoked or lost your old PGP key and you migrated to a
+new one before updating LDAP, you need to find a sponsor to create a
+ticket for you. The sponsor should create a ticket in
+[[trac||https://trac.torproject.org/projects/tor/newticket]] in the
+{{{Tor Sysadmin Team}}} component:
+* The ticket should include your username, your old PGP fingerprint
+  and your new PGP fingerprint.
+* Your PGP key needs to be on a public keyserver and be signed by at
+  least one Tor person other than your sponsor.
+* The ticket should be PGP signed with the current valid PGP key of
+  your sponsor.
