This is one of those things that can be done in multiple different
ways - all of which are "right".

If you can get mail today at the Embarq address, even though the
Earthlink address still works, there is no harm in making an Embarq
key now.  You can revoke the Earthlink key whenever you'd like -
personally, I'd do it when the Earthlink address stops forwarding.

There is one other way to do this that you might want to consider.
Instead of making a new key, just add a new user ID to your existing
key.  The end result is a key with two addresses on it.  Once the
Earthlink forwarding stops, revoke just the Earthlink user ID on the
key (not the whole key).
