depends on HOW you upgrade your System:
a so-called 'clean install' indded wipes-off EVERYTHING from your hard-drive. Not only iMovie, any other app, any other document, all music, photos, etc. After a clean-install you have to re-install ANY other app, and for sure all your 'personal belongings' - e.g. from some back-up.
a simple to perform upgrade keeps all data and apps untouched.
just purchase/download 10.8 in the appstore, click install - done.
MacOS is a UNIX derivate - OS, apps, data are handled seperately.
