Angular 5 project is unable to upgrade in to Angular 7

Question

My current Angular cli Version is 1.6.6 and Angular Version is 5.2.2

I am trying to update it to Angular 7 and new angular cli version is 7.3.6

When I try to upgrade using ng update @angular/cli, an error in console prints

The specified command update is invalid. For available options, see ng help.

Your global Angular CLI version (7.3.6) is greater than your local
version (1.6.6). The local Angular CLI version is used.

It seems like this update command has been removed. I have followed the official documentation.

Any suggestions to upgrade?

in which case, you should be on 1.7.x cli? possibly even 1.8.x now — mast3rd3mon, Mar 22 '19 at 11:11

Update the local version in your `package.json` too: `npm install @angular/cli -D` — Igor, Mar 22 '19 at 11:13
looks like they change the numbering again, 7.3.6 is the latest, 1.6.6 is older, so update the version in oyur package.json — mast3rd3mon, Mar 22 '19 at 11:13
@Igor what is the `--D` for? if its for saving to dev dependencies, its `--save-dev` — mast3rd3mon, Mar 22 '19 at 11:14
@Igor im pretty sure `--save-dev` is an alias for `--save-devDependencies` — mast3rd3mon, Mar 22 '19 at 11:16
Well the official update says exactly what needs to be done. https://update.angular.io/ But If you follow that, this error comes — Dulanjaya Tennekoon, Mar 22 '19 at 11:18
@mast3rd3mon [documentation of npm-install](https://docs.npmjs.com/cli/install), "-D, --save-dev: Package will appear in your devDependencies.". Admittedly I did have one to many `-` characters. — Igor, Mar 22 '19 at 11:18
@DulanjayaTennekoon did you run all 3 commands it says in order? `npm install -g @angular/cli`, `npm install @angular/cli` and `ng update @angular/cli`? — mast3rd3mon, Mar 22 '19 at 11:19
Well. found a related link too. https://github.com/angular/angular-cli/issues/9408 They had the same issue as of mine — Dulanjaya Tennekoon, Mar 22 '19 at 11:22
@Igor you were right. It worked. The issue was, previously it did not update the package.json — Dulanjaya Tennekoon, Mar 22 '19 at 11:39

There is an issue in the official documentation.

It says to run npm install @angular/cli but actually you need to run

npm install --save-dev @angular/cli@latest

This will update the package.json, so that you can continue from there.

After this, you can run ng update @angular/cli and so on.
