How to downgrade Symfony version?

@samara 

To downgrade the version of Symfony in your project, you will need to follow these steps:

1. Check the current version of Symfony by running the following command in your project directory:

1

symfony --version

1. Make a backup of your project. It is always a good idea to make a backup of your project before making any changes.
2. Open the composer.json file in the root of your project and find the "symfony/symfony" package.
3. Change the version constraint for the "symfony/symfony" package to the version you want to downgrade to. For example, if you want to downgrade to version 4.4, you would change the constraint to "4.4.*".
4. Run the following command to update the dependencies and install the new version of Symfony:

1

composer update symfony/symfony

1. If you have any custom code that is specific to the version of Symfony you are downgrading from, you will need to update it to be compatible with the new version. This may involve making changes to your code, updating dependencies, and/or updating configuration files.
2. Test your project to ensure that everything is working as expected with the new version of Symfony.

Note: Downgrading to a previous version of Symfony is not always possible, and may require significant effort. It is generally recommended to stay up to date with the latest version of Symfony to take advantage of new features and bug fixes.
