Description

Having this issue trying to do an ng update on a pretty stock angular 7 application to angular 8:

ng update @angular/cli
Your global Angular CLI version (8.0.0) is greater than your local
version (7.3.8). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".
                  Package "@angular/compiler-cli" has an incompatible peer dependency to "typescript" (requires ">=3.1.1 <3.3", would install "3.4.5").
Incompatible peer dependencies found. See above.

Also, do we have to do a git commit after every update operation??

ng update @angular/core
Repository is not clean.  Please commit or stash any changes before updating.

Also related to #13095

@jtsom, you can run multiple migrations as such: ng update @angular/cli @angular/core

[jtsom]

I did see #13095 but wanted to specifically target the new 8.0 (where it says it supports Typescript 3.4 - except where it doesn't....)

[jtsom]

I was able to get the update to run using the --force flag, but it looks like the operations that are run after the update (updating tsconfig.json, tslint.json, etc) were not run. How do I re-run those schematics to get everything up to date?

[alan-agius4]

You can run ng update @angular/cli--from 7 --to 8 --migrate-only

[jtsom]

Except:

ng update @angular/cli --from 7 --to 8 --migrate-only
