Sounds like you have to do 'upgrades'.

It should, because it's possible that you would need to move /etc files
and such.  But, stating what it *should* be able to do at this point is
a moot point.

Which is IMO the only 'acceptable' technical solution, and one many

Doesn't it seem like no matter how far we try to think ahead, something
always pops up that we never considered. :)

State their getting 2X performance, and the internal disk is being
replaced by something that is twice as big or something. :) :) :)
