@hiepxanh did not work for me

Same for me!

The migration is available in the Angular CLI starting with version 9.1.0. The project must be updated before the migration can be executed.

Please try executing the following within the project to update:
ng update @angular/cli @angular/core

For additional information regarding the release of Angular 9.1 please see: https://blog.angular.io/version-9-1-of-angular-now-available-typescript-3-8-faster-builds-and-more-eb292f989428

@clydin should I close issue or not? I resoved mine but other didn't sir.

[mburger81]

Yes I figured it out yesterday. Firstly we have to run the update and then the migration too.

In my opinion this is not clear from reading the article. But it could also be it's a language problem of mine.
Also it is strange, it is talking first about the migration and then how to update. It would be better if first we have the distribution about how to do the update, and then what to do if you also would like to migrate to tslint6.1
thx
