Upgrading to the latest version of Magento 2 is essential as running an older version of Magento 2 can leave your store vulnerable to security threats. In this article, we will provide a simple and complete guide on how to update Magento 2 to the latest version.

To update Magento 2, follow these steps:

Backup your files and database: Before performing any update, it’s crucial to back up your Magento 2 files and database. This step ensures that you can revert back to the previous version if something goes wrong during the update process.

Review the release notes:

Check the Magento 2 release notes to understand the changes and improvements included in the new version. This will help you assess the impact of the update on your store and identify any specific requirements or compatibility issues.

Disable maintenance mode:

If you have enabled maintenance mode previously, disable it to ensure your store is accessible during the update process. You can disable maintenance mode by removing the maintenance.flag file located in the root directory of your Magento installation.

Update dependencies:

If you are using Composer to manage your Magento installation, update your dependencies first. Open your terminal or command prompt, navigate to your Magento 2 installation directory, and run the following command:

composer update

This command updates all the dependencies specified in your composer.json file to their latest compatible versions.

Update Magento:

After updating the dependencies, run the following command to update Magento itself:

composer require magento/product-community-edition:<version> --no-update
composer update --ignore-platform-reqs

Replace <version> with the specific version number you want to update to (e.g., 2.4.3). The first command updates the composer.json file with the desired Magento version, and the second command performs the actual update.

Update the database schema:

After updating the codebase, run the following command to update the database schema:

php bin/magento setup:upgrade

This command applies any necessary database schema changes introduced in the new version.

Clear caches:

Clear the Magento cache to ensure that your store reflects the updated code changes. Run the following command:

php bin/magento cache:clean

Deploy static content:

If you are in production mode, deploy the static content by running the following command:

php bin/magento setup:static-content:deploy

This command generates the static files required for the front end of your store.

Reindex data:

Reindex your store’s data using the following command:

php bin/magento indexer:reindex

Reindexing ensures that your store’s data, such as product information and search indexes, are up to date.

Enable maintenance mode: Once you have completed the update process, enable maintenance mode again if desired. Create a maintenance.flag file in the root directory of your Magento installation.

That’s it! Your Magento 2 store should now be successfully updated to the new version. Remember to thoroughly test your store’s functionality after the update to ensure everything is working as expected.
