Perform an upgrade

You can upgrade on-premises deployments of the Adobe Commerce or Magento Open Source application from the command line if you installed the software by:

  • Downloading the Composer metapackage using the composer create-project command.
  • Installing the compressed archive.
NOTE

The following instructions show you how to upgrade using the Composer package manager. Adobe Commerce 2.4.2 introduced support for Composer 2. If you are attempting to upgrade from <2.4.1, you must first upgrade to a version that is compatible with Composer 2 (for example, 2.4.2) using Composer 1 before upgrading to Composer 2 for >2.4.2 upgrades. In addition, you must be running a supported version of PHP.

WARNING
The procedure for upgrading Adobe Commerce and Magento Open Source has changed. You must install a new version of the magento/composer-root-update-plugin package (see prerequisites). In addition, the commands for upgrading have changed from composer require magento/<package_name> to composer require-commerce magento/<package_name>.

Before you begin

You must complete the upgrade prerequisites to prepare your environment before starting the upgrade process.

Manage packages

NOTE
See the examples at the end of this section for help with specifying different release levels. For example, quality patches and security patches. If you cannot find these packages in Composer, contact Adobe Commerce Support.
  1. Switch to maintenance mode to prevent access to your store during the upgrade process.

    code language-bash
    bin/magento maintenance:enable
    

    See Enable or disable maintenance mode for additional options. Optionally, you can create a custom maintenance mode page.

  2. Starting the upgrade process while asynchronous processes, such as message queue consumers, are running may cause data corruption. To prevent data corruption, disable all cron jobs.

    Adobe Commerce on cloud infrastructure:

    code language-bash
    ./vendor/bin/ece-tools cron:disable
    

    Magento Open Source:

    code language-bash
    bin/magento cron:remove
    
  3. Start all message queue consumers manually to ensure that all messages are consumed.

    code language-bash
    bin/magento cron:run --group=consumers
    

    Wait for the cron job to complete. You can monitor the status of the job with a process viewer or by running the ps aux | grep 'bin/magento queue' command multiple times until all processes complete.

  4. Create a backup of the composer.json file.

    code language-bash
    cp composer.json composer.json.bak
    
  5. Add or remove specific packages based on your needs.

    For example, if you are upgrading from Magento Open Source to Adobe Commerce, remove the Magento Open Source package.

    code language-bash
    composer remove magento/product-community-edition --no-update
    

    You can also upgrade sample data.

    code language-bash
    composer require <sample data module-1>:<version> ... <sample data module-n>:<version> --no-update
    
    • Adobe Commerce:

      code language-bash
      composer require magento/module-bundle-sample-data:100.4.* magento/module-widget-sample-data:100.4.* magento/module-theme-sample-data:100.4.* magento/module-catalog-sample-data:100.4.* magento/module-customer-sample-data:100.4.* magento/module-cms-sample-data:100.4.*  magento/module-catalog-rule-sample-data:100.4.* magento/module-sales-rule-sample-data:100.4.* magento/module-review-sample-data:100.4.* magento/module-tax-sample-data:100.4.* magento/module-sales-sample-data:100.4.* magento/module-grouped-product-sample-data:100.4.* magento/module-downloadable-sample-data:100.4.* magento/module-msrp-sample-data:100.4.* magento/module-configurable-sample-data:100.4.* magento/module-product-links-sample-data:100.4.* magento/module-wishlist-sample-data:100.4.* magento/module-swatches-sample-data:100.4.* magento/sample-data-media:100.4.* magento/module-offline-shipping-sample-data:100.4.* magento/module-gift-card-sample-data:100.4.* magento/module-customer-balance-sample-data:100.4.* magento/module-target-rule-sample-data:100.4.* magento/module-gift-registry-sample-data:100.4.* magento/module-multiple-wishlist-sample-data:100.4.* --no-update
      
    • Magento Open Source:

      code language-bash
      composer require magento/module-bundle-sample-data:100.4.* magento/module-widget-sample-data:100.4.* magento/module-theme-sample-data:100.4.* magento/module-catalog-sample-data:100.4.* magento/module-customer-sample-data:100.4.* magento/module-cms-sample-data:100.4.*  magento/module-catalog-rule-sample-data:100.4.* magento/module-sales-rule-sample-data:100.4.* magento/module-review-sample-data:100.4.* magento/module-tax-sample-data:100.4.* magento/module-sales-sample-data:100.4.* magento/module-grouped-product-sample-data:100.4.* magento/module-downloadable-sample-data:100.4.* magento/module-msrp-sample-data:100.4.* magento/module-configurable-sample-data:100.4.* magento/module-product-links-sample-data:100.4.* magento/module-wishlist-sample-data:100.4.* magento/module-swatches-sample-data:100.4.* magento/sample-data-media:100.4.* magento/module-offline-shipping-sample-data:100.4.* --no-update
      
  6. Upgrade your instance using the following composer require-commerce command syntax:

    code language-bash
    composer require-commerce magento/<product> <version> --no-update [--interactive-root-conflicts] [--force-root-updates] [--help]
    

    Command options include:

    • <product> —(Required) The package to upgrade. For on-premises installations, this value must be either product-community-edition or product-enterprise-edition.

    • <version> —(Required) The version of Adobe Commerce or Magento Open Source that you are upgrading to. For example, 2.4.3.

    • --no-update —(Required) Disables the automatic update of the dependencies.

    • --interactive-root-conflicts —(Optional) Allows you to interactively view and update any out-of-date values from previous versions, or any customized values that do not match the version you are upgrading to.

    • --force-root-updates —(Optional) Overrides all conflicting custom values with the expected Commerce values.

    • --help —(Optional) Provides usage details about the plugin.

    If neither --interactive-root-conflicts nor --force-root-updates are specified, the command keeps the existing values that are in conflict and displays a warning message. To learn more about the plugin, refer to the Plugin Usage README.

  7. Update the dependencies.

    code language-bash
    composer update
    

Example - list available versions

To see the full list of available 2.4.x versions:

Magento Open Source:

composer show magento/product-community-edition 2.4.* --available | grep -m 1 versions

Adobe Commerce:

composer show magento/product-enterprise-edition 2.4.* --available | grep -m 1 versions

Example - Quality patch

Quality patches primarily contain functional and security fixes. However, they can sometimes contain new, backward-compatible features. Use Composer to download a quality patch.

Adobe Commerce:

composer require-commerce magento/product-enterprise-edition 2.4.6 --no-update

Magento Open Source:

composer require-commerce magento/product-community-edition 2.4.6 --no-update

Example - Security patch

Security patches contain security fixes only. They are designed to make the upgrade process faster and easier. Security patches use the Composer naming convention 2.4.x-px.

Adobe Commerce:

composer require-commerce magento/product-enterprise-edition 2.4.6-p3 --no-update

Magento Open Source:

composer require-commerce magento/product-community-edition 2.4.6-p3 --no-update

Update metadata

  1. Update the "name", "version", and "description" fields in the composer.json file as needed.

    note note
    NOTE
    Updating the metadata in the composer.json file is entirely superficial, not functional.
  2. Apply updates.

    code language-bash
    composer update
    
  3. Clear the var/ and generated/ subdirectories:

    code language-bash
    rm -rf var/cache/*
    
    code language-bash
    rm -rf var/page_cache/*
    
    code language-bash
    rm -rf generated/code/*
    
    note note
    NOTE
    If you use a cache storage other than the filesystem, such as Redis or Memcached, you must manually clear the cache there too.
  4. Update the database schema and data.

    code language-bash
    bin/magento setup:upgrade
    
  5. Disable maintenance mode.

    code language-bash
    bin/magento maintenance:disable
    
  6. (Optional) Restart Varnish.

    If you use Varnish for page caching, restart it:

    code language-bash
    service varnish restart
    

Check your work

To check whether the upgrade was successful, open your storefront URL in a web browser. If your upgrade was unsuccessful, your storefront does not load properly.

If the application fails with a We're sorry, an error has occurred while generating this email. error:

  1. Reset file system ownership and permissions as a user with root privileges.

  2. Clear the following directories:

    • var/cache/
    • var/page_cache/
    • generated/code/
  3. Check your storefront in your web browser again.
