You don't need new keys, but you need to move them around. The
situation is asymmetric: the source needs the private key, and the
destination needs the public key in authorized_keys.

Does this mean that you have to send the private key accross to second
machine ? using scp ?

What if there is more machines involved ? how do you copy several
id_dsa 's to one computer ?

Use only one private key per machine.. You Just need to add each public
key into all the authorized_keys of all the machines, including it own
public key. You can do this authorized_keys file for one computer first
and copy it on the other computers if you want.
