You don't really need to uninstall the platform, unless your disk is running out of space; just change your search path (that's actually done automatically at installation time). If you keep the old platform, you can test your latest (versions of) packages with a previous compiler. Note, that re-installing an old platform may cause a lot of trouble, because cabal-install might select incompatible versions of packages.
