You can install mediawiki *files* in a different folder and then in the
installation step:
a) Choose the same database. The latest mediawiki (currently 1.16.0)
will update your database schema, so you shouldn't try to use 1.9.3
anymore (it may work for *reading* on most pages, but doing edits from
both versions would be a recipe for disaster).

b) Install in the same database with a different prefix, so you get an
empty wiki. You then have two completely independent installs, even if
phisically they live in the same database.
