Using New Angular6 Ng Update Feature

Everyone who using new angular knows that it depends on lot of packages - the @angular ones, rxjs, typescript and more. With so many dependencies- it might be hard job when trying to update, since some versions of some packages will not play with certain versions of other. (I call it dependency hell)

For solving this problem angular team added

ng update

command which should upgrade all the packages at once.
(Available from Angular CLI 1.7)

Experiment

Since it is interesting to play with new features, i decided to use this command for upgrading dependencies of one of my experimental projects. Its dependencies were like:

    "@angular/animations": "6.0.0-beta.7",
    "@angular/cdk": "6.0.0-beta.4",
    "@angular/common": "6.0.0-beta.7",
    "@angular/compiler": "6.0.0-beta.7",
    "@angular/core": "6.0.0-beta.7",
    "@angular/forms": "6.0.0-beta.7",
    "@angular/http": "6.0.0-beta.7",

And i expected that they will be upgraded to current 6.0.0-rc.3 version... After running command i got following message:

I guess that means the upgrade can be made only to stable version (not rc and not beta)

Well looks like angular guys still have some work to do...
