There is a problem with simply providing another address like that. There is no proof that you are the same person as the one that signed with 3KN...pbc. It is possible that you have gained control of the account after the the first signed message. So, if I had to verify you, I would not accept a message signed with 17F...3EW. The better way would be to sign something like "Leaving as well a legacy address, 17FRGunjF63qhzhrc5E12hU1Y2txeUR3EW, for the sake of compatibility." with the original address to prove that the new address is acceptable to owner of the original address.
Thank you for letting me know. In that case, I will take your advice.
