In general, I like the whole idea of using random/special ports for the
duration of the upgrade.  I agree that we need to keep the ability to
check the existing clusters.  My gut feeling is this: keep the existing
port options just as they are, so --check works just fine, etc.  Use
*only* long-options for the "ports to use during the actual upgrade" and
discourage their use- we want people to let a random couple of ports be
used during the upgrade to minimize the risk of someone connecting to
one of the systems.  Obvioulsy, there may be special cases where that's
not an option, but I don't think we need to make it easy nor do I think
we need to have a short option for it.
