What is Magento Setup Upgrade?

Magento Setup Upgrade is an essential process for maintaining and enhancing Magento 2 e-commerce stores.

Magento Setup updates the database schema and data to align with the latest version of Magento or installed modules. Before upgrading your Magento 2 store, it's essential to:

• Back up the current Magento installation and database.

• Review the latest Magento version release notes.

• Test the upgrade in a staging environment before you upgrade your Magento 2 store.

• Ensure all installed modules are compatible with the new version.

Magento 2 upgrades can be complex, especially for stores with many custom extensions. After the upgrade, thorough testing is necessary to ensure all store features function correctly. It includes checking the front end, back end, and any custom modules or integrations.

Benefits of Upgrading Magento Setup

1. Enhanced Security

Magento regularly releases security patches to address vulnerabilities. For example, the SUPEE-11346 patch in 2021 fixed critical issues like remote code execution vulnerabilities. By applying these patches, stores protect against potential data breaches or malware injections. It is essential for maintaining customer trust. It also helps avoid costly security incidents.

2. Improved Performance

Recent Magento versions have introduced features like asynchronous indexing and GraphQL support. Asynchronous indexing allows catalog updates without blocking front-end operations. It reduces downtime. GraphQL enables faster, more efficient API calls. It mainly benefits mobile apps and headless implementations. These improvements can lead to faster page load times and a smoother shopping experience. Consequently, they may increase conversion rates.

3. Access to New Features

Magento 2.4 introduced B2B capabilities like company accounts, requisition lists, and quote management. These features allow businesses to expand into B2B markets. They achieve this without requiring extensive custom development. Another example is the Page Builder introduced in Magento 2.3. This tool simplifies content creation for non-technical users.

4. Better Compatibility

Each Magento version supports specific PHP versions. For example, Magento 2.4.4 supports PHP 8.1. This version offers improved performance and new language features. Staying current ensures compatibility with the latest PHP versions. It allows stores to benefit from language-level improvements. It also provides access to security updates.

5. Enhanced User Experience

Recent updates have improved the admin panel's usability. For instance, Magento 2.4 introduced a new media gallery. This streamlined image management. On the front end, enhancements like improved checkout flows have been made. Native support for Progressive Web Apps (PWAs) has also been added. These improvements have significantly enhanced the customer experience in Adobe Commerce. It leads to higher conversion rates.

6. SEO Benefits

Magento updates often align with evolving SEO best practices. Recent versions have improved schema markup implementation. It helps search engines better understand and display product information in search results. They've also enhanced URL structure options and sitemap generation. These improvements contribute to better search engine visibility for your Magento 2 store.

How to Upgrade Magento 2 via Command Line

Step 1: Enable Maintenance Mode

1. Log in to your Magento server as the Magento file system owner.

2. Run the following command:

   php \<your Magento install dir\>/bin/magento maintenance:enable\

Step 2: Update Magento Core Files and Dependencies

1. Navigate to your Magento installation directory:

   cd /var/www/html/magento2\

2. Update Magento and its dependencies:

   composer require magento/product-community-edition \<new\_version\> \--no-update\ composer update\

   Replace <new_version> with your target Magento version (e.g., 2.4.5).

3. Enter your authentication keys when prompted.

Step 3: Clear Cache and Generated Files

1. Remove cached and generated files from the folder to ensure a clean upgrade.

   rm \-rf \<Magento install dir\>/var/cache/\* rm \-rf \<Magento install dir\>/var/page\_cache/\*\ rm \-rf \<Magento install dir\>/generated/code/\*\

2. If using external cache storage (e.g., Redis), clear it manually.

Step 4: Update Database Schema and Data

Run the setup upgrade command:

php bin/magento setup:upgrade\

Step 5: Compile Code and Deploy Static Content

1. Compile the code:

   php bin/magento setup:di:compile\

2. Deploy static content:

   php bin/magento setup:static-content:deploy\

Step 6: Disable Maintenance Mode

Turn off maintenance mode:

php bin/magento maintenance:disable\

Step 7: Refresh Cache

Clear and refresh the cache:

php bin/magento cache:clean php bin/magento cache:flush\

Step 8: Verify the Upgrade

1. Check your Magento version:

   php bin/magento \--version\

2. Log in to the admin panel and check for any error messages.

3. Browse your storefront to ensure everything is functioning correctly.

Common Compatibility Challenges

1. Extension Conflicts:

Third-party extensions may use deprecated methods or hooks that are removed in newer Magento versions. For example, Magento 2.4.0 removed the \Magento\Framework\DB\Adapter\Pdo\Mysql::closeConnection() method. Extensions relying on this method would break after upgrading your Magento 2 store.

Example: A popular product recommendation extension might use outdated catalog indexing methods. After upgrading, this could lead to incorrect product suggestions. It might even cause the extension to stop functioning entirely.

Impact: This can disrupt critical store functionalities. These include

• Checkout processes

• Product displays

• Customer account features

Such disruptions can lead to lost sales. They may also result in poor user experience.

2. Custom Code Incompatibility:

Custom themes or modules often override core Magento classes or templates. When these core elements change in an upgrade, it can break the custom code.

Example: A store might have a custom checkout process. This process could override Magento's default \Magento\Checkout\Model\Session class. Magento might change this class's structure in an upgrade. If this happens, the custom checkout could malfunction. It could prevent customers from completing purchases.

Impact: This can lead to broken layouts. It can also cause non-functioning features. In some cases, it might even result in site-wide errors. These issues can severely impact the store's usability. Fixing these problems may require significant development work.

3. PHP Version Mismatch:

Magento upgrades often require newer PHP versions to leverage improved language features and security updates.

Example: Magento 2.4.4 requires PHP 7.4 or higher, while a store might be running on PHP 7.2. This mismatch can cause fatal errors due to the use of PHP features that are not available in older versions.

Impact: This can prevent the Magento application from running at all. It may result in downtime until the server environment is updated. Updating the PHP version may also require updating other PHP extensions. All site functionalities would need to be tested for compatibility with the new PHP version.

4. Database Schema Changes:

Magento upgrades can introduce new tables and columns or change existing data structures.

Example: Magento 2.3 introduced a new table, ‘inventory_source_item.' It was part of the Multi-Source Inventory (MSI) feature. Upgrading to this version would require migrating existing inventory data. The data would need to be moved to the new structure.

Impact: These changes can lead to data integrity issues if not handled correctly. They can also cause performance problems. Custom reports might break after an upgrade. Third-party integrations that directly query the database could be affected. These might return incorrect data after the update.
