How to upgrade symfony minor version (4.1 to 4.2)

问题

I just want to know which is the proper way to upgrade symfony a minor version.

In the documentation https://symfony.com/doc/current/setup/upgrade_minor.html it says just to upgrade symfony/symfony package in composer, but I don't have this package, instead I have various symfony/framework-bundle, symfony/form, etc.

What I've done so far is to upgrade all symfony/XXX to the new version.

Also I had to create a new project with the 4.2 version in other folder, and copy the files .gitignore, public/index.php, config/bootstrap.php and src/kernel.php to the original project as these files has changed from 4.1 to 4.2, but I think this should not be the way to do it.

Should I have to remove all symfony/XX packages and replace them with symfony/symfony?

Will this upgrade also the files public/index.php, config/bootstra.php, etc?

Thank you

In my case I was updating to 4.2 from 4.1.11 and some new files from 4.2 for some reason weren't automatically created. Also, there are a few changes in environment files that I consider very important.

I think the best and cleanest way to do this to do the following:

Instructions

Update composer.json

"extra": {
    "symfony": {
        "allow-contrib": false,
        "require": "4.2.*"
    }
}

Update dependencies composer update "symfony/*"
Create a new config/bootstrap.php file with this code.
Update public/index.php file with this code.
Update .gitignore

Remove

###> symfony/framework-bundle ###
/.env

Add

###> symfony/framework-bundle ###
/.env.local
/.env.local.php
/.env.*.local

Rename .env to .env.local
Rename .env.dist to .env

-- Update 30/05/19 --

Update bin/console file with this code

Testing with PHPUnit

Follow this extra steps if you are using PHPUnit in your application (Recommended):

Create a new .env.test and set your variables for test environment.
Update phpunit.xml.dist with this code.

Important

You should notify about the environment files changes to your team and they should make a backup of their current configuration before pulling the changes because it will override the .env file.

Just check your composer.json. I just did same and only had to raise the minor. Then I’ve ran composer update and I succeeded.

I always follow the guides.
