Updating Pimcore

Our Backward Compatibility Promise

Since we're building on top of Symfony and in an app, Pimcore and Symfony code get mixed together, it makes sense that we're adopting the same backward compatibility promise for PHP code.

For further information on how you can ensure that your application won't break when upgrading to a newer version of the same major release branch, please have a look at

Upgrading within Version 11


We recommend using the Pimcore Platform Version. Details see here.

  • Carefully read our Upgrade Notes before any update.
  • Check your version constraint for pimcore/pimcore in your composer.json and adapt it if necessary to match with the desired target version.
  • Run COMPOSER_MEMORY_LIMIT=-1 composer update
  • Clear the data cache bin/console pimcore:cache:clear
  • Run core migrations: bin/console doctrine:migrations:migrate --prefix=Pimcore\\Bundle\\CoreBundle
  • (optional) Run migrations of your app or bundles

Upgrading from earlier Versions
