Update angular 8 to 10 using cli

Question

Using the ng update command to update the angular to the latest version. Keep getting the peer dependency issues.

I tried with the --force command, however, there were lots of different issues

                  Package "@angular-redux/form" has an incompatible peer dependency to "@angular/core" (requires "^6.0.0" (extended), would install "10.0.14").
                  Package "tsickle" has an incompatible peer dependency to "typescript" (requires "~3.8.2", would install "3.9.7")
                  Package "@angular-redux/form" has an incompatible peer dependency to "@angular/common" (requires "^6.0.0" (extended), would install "10.0.14").
                  Package "@angular-redux/form" has an incompatible peer dependency to "@angular/compiler" (requires "^6.0.0" (extended), would install "10.0.14").
                  Package "@angular-redux/form" has an incompatible peer dependency to "@angular/forms" (requires "^6.0.0" (extended), would install "10.0.14").
                  Package "@swimlane/ngx-datatable" has an incompatible peer dependency to "@angular/platform-browser" (requires "<9.0.0" (extended), would install "10.0.14").
                  Package "@angular-redux/router" has an incompatible peer dependency to "@angular/router" (requires "^6.0.3" (extended), would install "10.0.14").
                  Package "tsickle" has an incompatible peer dependency to "typescript" (requires "~3.8.2", would install "3.9.7").


✖ Migration failed: Incompatible peer dependencies found.
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.

Please check this out: Upgrade to Angular 9

You may follow this to upgrade from Angular 8 to 10 directly.

If that doesn’t work, upgrade to Angular 9 first, then use same strategy to upgrade from Angular 9 to 10.

And if that doesn’t work, I would say create brand new Angular 10 app and migrate components one by one. If it’s medium size app, it shouldn’t take more than 4 hours. This exercise will help you clean up some unnecessary code as well. Check this out: Upgrade from Angular 4 to 8

Hope this helps.
