I don't know if sshd has a concept for comments in the known_hosts
file.  It would probably work anyway by making it not an exact match.
 But I'd probably just copy the old file to a different name if I
wanted access to the old contents.   You should never need them as
long as you manually connect and accept the new key, unless you are
concerned with the security implications that a different/fake  server
might be trying to intercept your connection and has hijacked the
name/ip address that you used to connect.
