Upgrade your Adobe Commerce or Magento Open Source application from the command line.

• After reviewing system requirements, you must complete the following prerequisites before upgrading your system:
• Update all software
• Verify that a supported search engine is installed
• Convert database table format
• Set the open files limit
• Verify that cron jobs are running
• Set DATA_CONVERTER_BATCH_SIZE
• Verify file system permissions
• Set the pub/ directory root
• Install the Composer update plugin
• Switch to maintenance mode to prevent access to your store during the upgrade process.

bin/magento maintenance:enable

• To prevent data corruption, disable all cron jobs.

Adobe Commerce on cloud infrastructure:

            ./vendor/bin/ece-tools cron:disable

Magento Open Source:

bin/magento cron:remove

• Start all message queue consumers manually to ensure all messages are consumed.

            bin/magento cron:run --group=consumers

• Create a backup of the composer.json file.

             cp composer.json composer.json.bak

• Add or remove specific packages based on your needs.

           composer remove magento/product-community-edition --no-update

          You can also upgrade sample data.

           composer require <sample data module-1>:<version> ... <sample data module-n>:<version> --no-update

• Upgrade your instance using the following composer require-commerce command syntax:

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

• Update the dependencies.

            composer update

• Clear the var/ and generated/ subdirectories:

            rm -rf var/cache/*

            rm -rf var/page_cache/*

            rm -rf generated/code/*

• Update the database schema and data.

            bin/magento setup:upgrade

• Disable maintenance mode.

bin/magento maintenance:disable

• Restart Varnish.

        If you use Varnish for page caching, restart it: service varnish restart.

• Open your storefront URL in a web browser to check whether the upgrade was successful. If your upgrade were unsuccessful, your storefront would not load properly.

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

• Reset file system ownership and permissions as a user with root privileges.
• Clear the following directories:
  • var/cache/
  • var/page_cache/
  • generated/code/
• Check your storefront in your web browser again.
