How can I upgrade Angular to the most recent version?

Upgrading an Angular application to a newer version involves the following steps:

Determine the version you want to upgrade to: Before you start the upgrade process, it’s important to know which version you want to upgrade to and ensure that it is compatible with your current application.
Update Angular CLI: To upgrade your Angular application, you need to have the latest version of Angular CLI installed. You can update it by running the following command in your terminal:

ng update @angular/cli

Update Angular packages: Next, you need to update the Angular packages in your application. You can use the following command to update all Angular packages:

ng update @angular/core

Check for compatibility issues: After updating the packages, it’s important to check if there are any compatibility issues. You can use the ng update command to check for any issues and update the necessary code:

ng update

Update TypeScript version: If the Angular version you want to upgrade to requires a newer version of TypeScript, you need to update it as well. You can do this by updating the typescript version in your package.json file.
Test the application: Once you’ve completed the above steps, it’s important to test your application thoroughly to make sure everything works as expected.
Document the changes: Finally, document the changes you made during the upgrade process to make it easier to maintain your application in the future.

Note: The specific steps required to upgrade an Angular application may vary based on the complexity of the application and the extent of the changes made in the new version of Angular. It’s recommended to create a backup of your application before starting the upgrade process, in case something goes wrong.
