Practical TypeScript Migration
This is a fairly short video course by Steve Ognibene, and it’s available here on Pluralsight. The course is not targeted at any particular framework, though the application that he’s converting during the course, was written using KnockoutJS.
Preparing for and Migrating Applications to Angular 2
A course by Joe Eames clocking in at 2 hours and 57 minutes in total. This course is about migrating from AngularJS (= 1.x) to Angular (2+). I’ve gone through the whole course, but I might actually re-watch it later on if I start considering doing a proper migration sometime in the future. The course can be found here on Pluralsight.
Angular docs about migration
The Angular team have an article on migrating from AngularJS to Angular, and it’s definately worth taking a look at that one if you’re going to pursue a migration.
