Is it safe to update Angular from 7 to 8 in a Ionic4 app?

Hi,
I’ve an Ionic4 app that uses these libraries:

    "@angular/common": "^7.2.2",
    "@angular/core": "^7.2.2",
    "@angular/forms": "^7.2.2",
    "@angular/http": "^7.2.2",
    "@angular/platform-browser": "^7.2.2",
    "@angular/platform-browser-dynamic": "^7.2.2",
    "@angular/router": "^7.2.2",

Now I’d like to install some librarries like (Fontawesome) that require Angula 8 at least.
According to you, is it safe to update these libraries?

Is there a procudure to update Angular in an Ionic app?

Thank you

While you wait foe an exact answer:
I would recommend to upgrade to the latest Ionic and latest Angular. I’m using Angular 11.1 in all my Ionic apps.
