I haven't been around NAV long enough to know this, so looking for some thoughts. Although I know no one can give me a definite answer.
Usually certifications are good for two versions or until Microsoft stops supporting the version of the software you are certified in. For example 3.7 is no longer supported so those certifications don't help you anymore. Only 4.0 and 5.0.
My question is with NAV 2009 coming out in December, how long do you think it will be before the 4.0 certifications are no longer supported? Ordinarily I would just say they would be dropped in a few months, but 2009 isn't really offering any functionality changes, only technical. So I can see dumping Install/Config and Development for 4.0. They haven't even come out with tests for 5.0 on about half the exams. #-o
So to sum it up, do you think it's worth it to take a 4.0 exam in something like Service Management when when no 5.0 exam exists and there's nothing that's changed in 2009? There probably won't be any changes until NAV2011. Or will it just be dumped in due course? Again, I know there's no definite answer. Just wondering what experiences you may have had with Microsoft on issues like this.
