As a data point, pg_upgrade has an option to do an in-place upgrade
which
reuses the vast majority of the data files as they are on disk, rather
than
making a copy.
It's useful for larger databases, and for situations where you don't
have
much space.
BUT, you *do* have backups don't you?
Because stuff *can* go wrong, even though it's not common. ;)
