tor keys

[gabrix]

I have formatted the machine where tor was now i have a new install for
my tor server argo666tor.
my questions is :
now i have new keys but the fingeprint is the same of before , is this
right ?

Noooooooooooo!
I read too late the documentation i should have kept the keys , now i
have the old fingerprint , i have lost the new fingerprint  and i made a
disaster ... i 'll make a new tor install wait for the new
fingerprint,pardon!
