However, you may be infringing the license terms (but nobody will
annoy you with this) and you may loose upgrade or maintenance rights
on the older machine.

Those rights will be transfered to the newer machine.

No, this is technically impossible.

That is reasonnable.

By the way, you could also have both v7 and v8 on the newer machine
and forget the older one.

For the people who have a working v5.2 on an old machine : it is worth
keeping it for comparison.
v6 you can throw away because it is merely v7 + bugs.
