My question, too!
I am also doing an "upgrade of an upgrade". So I have:
2.x full key,
3.0 upgrade key, and
4.0 upgrade key.
I kept all the license keys so far, but I deleted the dmg files of the old (2.x) builds of Parallels. Will I be able to install Parallels fresh in the future? Will I then have to supply the keys in sequence? If I stay loyal to your product for a few years, will I need to keep *all* intermediate keys?
Thanks!
