I haven't done this particular route, so I had a look on Youtube to get an idea of what it was like. All told, it looks very pretty and the huts are excellent. A couple of observations. The path the man who made the video took would appear to be very steep, the website you found says daily variations in altitude of around 2000 mts, which is quite a lot, particulaly if you aren't very experienced. Even if you are fit, you may have trouble keeping up with the signposted times.
On the video I found there are a couple of sections with fixed cables for added security, like a hand rail, but that's no big deal, and it looks like at least one section has replaced a ladder with a steel staircase, which is becoming more common in the Alps. From what I could see, it's technically very simple, but very hard work. There seemed to be a lot of scree to cover once you get above the treeline which makes things a bit harder.
This is one I would happily do, but ony after spending a week or so doing easier ones first.
Hope this helps
