# Objective - closes #15866 ## Solution - Simply migrate where possible. ## Testing - Expect that CI will do most of the work. Examples is another way of testing this, as most of the work is in that area. --- ## Notes For now, this PR doesn't migrate `QueryState::single` and friends as for now, this look like another issue. So for example, QueryBuilders that used single or `World::query` that used single wasn't migrated. If there is a easy way to migrate those, please let me know. Most of the uses of `Query::single` were removed, the only other uses that I found was related to tests of said methods, so will probably be removed when we remove `Query::single`.
