They are backwards compatible formats, so why do you want to change? If you are concerned that the old password hash is insecure (if it's an ancient DES password, this is true), then you will need to generate a new password for each affected account. One way to do this is by using password expiry to force a change on next user login (see e.g. pw(8)). Kris
