hosted engine supports running on *multiple* nodes, providing out of the 
box HA between them.
the setup should ask you if this is the second host and take care of all 
the right things to copy.

(iirc, copying by yourself without knowing the internal details is risky 
if the first host could still be used. better to add the 2nd host per 
procedure, then keep or remove the 1st host)
