As for restoring backwards (restoring a database from a newer version to an older one) is not supported. I think it is possible but not pretty.
It's not that it's not supported, it's outright not possible, pretty or otherwise. You have to recreate the DB on the lower version.
Not that the OP asked about restoring to a lower version.
