Just run ng update it will suggest the necessary steps as shown below.

    We analyzed your package.json, there are some packages to update:
      Name                               Version                  Command to update
     --------------------------------------------------------------------------------
      @angular/cli                       11.0.0-next.2 -> 11.0.0  ng update @angular/cli
      @angular/core                      11.0.0-next.2 -> 11.0.0  ng update @angular/core
    There might be additional packages which don't provide 'ng update' capabilities that are outdated.
    You can update the addition packages by running the update command of your package manager.

As I am already using Angular 11.0.0-next.2 version it’s suggesting me to run ng update @angular/cli and ng update @angular/core.

First I ran ng update @angular/cli. And it got succeeded.

After running ng update @angular/core I got following errors it’s failed to upgrate to Angular 11 version.

Peer dependency warnings when installing dependencies means that those dependencies might not work correctly together.
You can use the '--force' option to ignore incompatible peer dependencies and instead address these warnings later.

Troubleshooting Angular 11 update errors.

I was kind of shocked to see the errors because every time I update to new version of Angular, I will get errors.

The first step I did to fix the error is to run command with –force flag.

ng update @angular/core --force

Then it gave one more error Error: EPERM: operation not permitted.

Angular 11 is in currently in pre release state. As of now there is no official information regarding Angular 11 release date.

However our applications can be update to Angular 11 pre release versions.

If your application is in Angular 10 and want to update it to Angular 11 you can use following ng update command to upgrade to version 11 of Angular.

ng update --next

Just add --next flag as Angular 11 version is in pre release state.

I strongly suggest you to update your app to Angular 10 before upgrading to Angular 11. Update to Angular 10

The command will update the app to Angular 11 or suggest steps to update it to Angular 11.

    We analyzed your package.json, there are some packages to update:
      Name                               Version                  Command to update

      @angular/cli                       10.1.2 -> 11.0.0-next.2  ng update @angular/cli --next
      @angular/core                      10.1.2 -> 11.0.0-next.2  ng update @angular/core --next

So we need to update Angular cli to the version 11.0.0-next.2 version

ng update @angular/cli@11.0.0-next.2 --force

As Angular 11 is in pre release state, its better to add version to the command.
