I'm hopeful it will work better (but not ready to be a guinea pig). They
finally made some improvements to the migration process. New profiles no
longer automatically create a new, blank PST file but provide an option to
connect to a previous file. That procedure works quite well and creates no
ghosts.

Upgrade installations are and always have been problematic with Outlook,
even more so with betas. Best practice is install Outlook clean and use
the supported methods for migrating your Outlook data (posted here
daily).
If you decide to experiment with an upgrade installation anyway, at the
very least you should create a new Outlook profile from scratch and back
up all data thoroughly ahead of time.

To satisfy my own curiosity, I'm going to be choosing "Upgrade" for my
installation of Office 2010 because I want to see what happens to the mail
profile and be aware of what problems arise.
