For an update to angular 8 itself you can just run ng update @angular/cli @angular/core.

Problematic is the naticescript-angular package (Version 8.0.0). There are some more things to do as described in this article: https://www.nativescript.org/blog/nativescript-now-supports-angular-8

So an update of the schematics should proceed all this steps.
