Repro steps

• Step 1 - Install CLI rc.4 and see this message

================================================================================
An old CLI configuration has been detected, which needs to be updated to the latest version.

Please run the following command to update this workspace:
  ng update @angular/cli --migrate-only --from=1
================================================================================

• Step 2 - Run ng update @angular/cli --migrate-only --from=1 as suggested and get this error

Schematic input does not validate against the Schema: {"dryRun":false,"migrateOnly":true,"from":1,"force":false,"all":false,"next":false,"registry":"http://registry.npmjs.org/"}
Errors:

  Data path ".from" should be string.

• Step 3 - Run ng update @angular/cli --migrate-only --from="1" and get the same error
• Step 4 - Run ng update @angular/cli --migrate-only --from='1' and get the same error

Desired behavior

The command recommended by the CLI message should run without error.

Mention any other details that might be useful (optional)

N/A

[pinalbhatt]

Me too getting same error.

ng update @angular/cli --migrate-only --from=1.7.4 seemed to work, but it is not what was recommended. I was upgrading from Angular CLI 6.0.0-beta.5.

ng update @angular/cli --migrate-only --from=1.7.4 not work

[benouat]

The nodejs module used behind the scene to get command line parameters is probably wrongly casting --from=1 to boolean instead of keeping it as a string.

ng update @angular/cli --migrate-only --from=1.7.4 just worked for me

[nik-base]

Use your previous version of angular-cli instead of 1 for the --from attribute.
So it would look something like this.
ng update @angular/cli --migrate-only --from=<previous_version_of_cli>
The new angular cli doesnt have angular-cli.json, it is replaced by angular.json.

[filipesilva]

Yes it looks like our arg parsing isn't reading --from=1 as a number. There is a fix incoming in #10315. Sorry about that :/

[dkaushikl]

after above command, it generates a new error while build or serve application
Cannot read property 'config' of null

[mantonik]

Hi, as I understand fix is in new build, but what I should do now to move forward?

When I do
ng update @angular/cli --migrate-only
Updating package.json with dependency @angular/cli @ "1.7.4" (was "1.5.0")...

but ng server still is giving a problem-related cli version

I tried
[mariusz admin.angular5]$ ng update @angular/cli --migrate-only --from=1.5.0
/Users/mariusz/dev/selenium_testing_portal/projects/admin.angular5>
[mariusz admin.angular5]$ ng update @angular/cli --migrate-only --from="1.5.0"
/Users/mariusz/dev/selenium_testing_portal/projects/admin.angular5>

but those look like no effect

my current config

[mariusz admin.angular5]$ ng --version

Thank you for suggestion

@mantonik I would try ng update @angular/cli --migrate-only --from=1.7.4 and if that doesn't work, try upgrading to 1.7.4, getting things working, and then re-running the update command with 6.0.0-rc.4.
