If this _is_ Windows, the question is discussed in detail in the rw-FAQ. That document also discusses how to install packages into a site or personal library which can make upgrading easier.

Another consideration not told to us was whether one wants to keep around a working copy of the older version. My dept does so (so students can use a consistent version when preparing their theses, for example), and that affects the choice of strategy.
