A full uninstall is of course not needed, but it might be cleaner to simply install in a different location and use something like modules to handle setting up the environment in a suitable manner. One thing that you can't skip though is recompiling your applications. Something built against openmpi-x.y is not likely to work with openmpi-x.z.
