Upgrade symfony 2.1 to 2.3 composer.json - symfony

Question

I'm trying to upgrade from 2.1 to 2.3 but getting composer error:
Your requirements could not be resolved to an installable set of packages.
I tried to upgrade just the framework first without bundles by replacing "symfony/symfony": "2.1." with "symfony/symfony": "2.3." in composer.json and running
php composer.phar update symfony/symfony
it didn't work so I tried to update jms/security-extra-bundle first, but it didn't work
php composer.phar update
didn't work neither, I teied "symfony/symfony": "2.2.*" as well
here my composer.json, what should I change?
{
"name": "symfony/framework-standard-edition",
"description": "The \"Symfony Standard Edition\" distribution",
"autoload": {
"psr-0": { "": "src/" }
},

Answer 1

Change the version constraints for the following packages to 2.3:
symfony/symfony
doctrine/doctrine-bundle
symfony/assetic-bundle
symfony/swiftmailer-bundle
symfony/monolog-bundle
sensio/distribution-bundle
sensio/framework-extra-bundle
sensio/generator-bundle
And the other packages as such
friendsofsymfony/jsrouting-bundle: 1.5.*
You'll also need to add the following packages:
incenteev/composer-parameter-handler
The post-install-cmd and post-update-cmd arrays would then need as the first command
"Incenteev\\ParameterHandler\\ScriptHandler::buildParameters",
A config.bin-dir definition should be provided for vendor executables
"config": {
"bin-dir": "bin"
},
Since Symfony 2.3 is an LTS version (Long Term Support), you can either change the minimum-stability setting to stable or prefer stable packages if they are available
"prefer-stable": true,
So your composer.json file should look like this:
{
"name": "symfony/framework-standard-edition",
"description": "The \"Symfony Standard Edition\" distribution",
"autoload": {
"psr-0": { "": "src/" }
},
"require": {

"doctrine/orm": ">=2.2.3,<2.4-dev",

"twig/extensions": "1.0.*",
"symfony/assetic-bundle": "2.3.*",
"symfony/swiftmailer-bundle": "2.3.*",
"symfony/monolog-bundle": "2.3.*",
"sensio/distribution-bundle": "2.3.*",
"sensio/framework-extra-bundle": "2.3.*",
"sensio/generator-bundle": "2.3.*",
"incenteev/composer-parameter-handler": "~2.0",
"jms/security-extra-bundle": "dev-master",
