I had a little app written in NS-Vue last year and then didn't touch it for awhile. Last week I clone the repo and want to continue my previous work. With the same machine, same environment as when I last worked on it. I suppose it will compile. But when I try to build it, it doesn't work. Days after I realised NS is now version 8 (my project was 6.7.4) . I can't find any documentation on how to migrate v6 -> v8. Eventually I come across this article and know its time to learn other technology. Project created by NS is fragile and not promising.
