i have to update an angular 7.x project to angular 8.2.0, so i've read online of ng update.
I have a global angular version equal to my update target version (8.2.0) but ng update forces me to update to the latest version.
Your global Angular CLI version (8.2.0) is greater than your local
version (7.3.5). The local Angular CLI version is used.
To disable this warning use "ng config -g cli.warnings.versionMismatch false".
We analyzed your package.json, there are some packages to update:
Name Version Command to update
---------------------------------------------------------------------------------------
@angular/cdk 7.3.3 -> 13.3.1 ng update @angular/cdk
@angular/cli 7.3.5 -> 13.3.0 ng update @angular/cli
@angular/core 7.2.8 -> 13.3.0 ng update @angular/core
@angular/core 7.2.8 -> 7.2.16 ng update @angular/core
@angular/fire 5.1.1 -> 7.3.0 ng update @angular/fire
@angular/material 7.3.3 -> 13.3.1 ng update @angular/material
@nguniversal/aspnetcore-engine 7.1.1 -> 8.2.6 ng update @nguniversal/aspnetcore-engine
@nguniversal/express-engine 7.1.1 -> 13.1.0 ng update @nguniversal/express-engine
@ngx-i18nsupport/tooling 1.1.2 -> 8.0.3 ng update @ngx-i18nsupport/tooling
ng-mocks 7.7.0 -> 13.3.0 ng update ng-mocks
There might be additional packages that are outdated.
Run "ng update --all" to try to update all at the same time.
Is there a way to do this using ng update --all or not? Do I have to use Angular update guide?
I have also tried ng update @angular/cli --from="7.3.5" --to="8.2.0" but it does not work.

That is because when you do ng update you are not defining a specific version.
You should use something like ng update @angular/core@10 @angular/cli@10 etc...
Its not recommended to go from Angular 7 to Angular 13 in a single update, instead you should go version by version like:
Follow this Angular Update Guide and you should be fine, at the bottom you have specific instructions you should do before each update https://update.angular.io/
