The following instructions show you how to upgrade Magento using Composer.
- Magento 2.4.2 introduced support for Composer 2.
- If you are attempting to upgrade from Magento <2.4.1(“below 2.4.1” for example 2.4.0, 2.3.9, …), you must first upgrade to a version of Magento that is compatible with Composer 2 (for example, 2.4.2) using Composer 1 before upgrading to Composer 2 for Magento >2.4.2 (above 2.4.2 version) upgrades.
Prerequisites to prepare environment before starting the upgrade process:
