The best reason to keep your old keypair around is pretty simple: "what
does it hurt?"

If you delete your keypair, then if anyone sends you traffic encrypted
to that keypair you'll be unable to read it.  If you keep your keypair,
then you can.  And it's not as if it takes up a lot of room on your hard
drive or impairs GnuPG's performance.  :)
