Incremental updates may require more time to complete, as an API may be refactored multiple times over many versions. However, the confidence in moving incrementally is well worth it IMHO. If you don't have an extensive enough test suite or poor/missing QA process (or both!), doing a big bang upgrade is going to both be extremely painful and very error prone. It's worthwhile to keep up to date. It's probably not worthwhile to upgrade ASAP after a release, but you don't want to wait too long.
