1. Upload Magento 2 Manually

By manually uploading the most recent Magento 2 version to the root directory, you can upgrade Magento 2 to the latest version. This is the simplest way to use many upgrading methods. To manually upgrade Magento 2 simply follow these steps:

Step 1. Download the Latest Magento 2 Version

Install the most recent version of Magento 2 by downloading the zip file and placing it in the root directory. If the system prompts you to replace existing files, select “Yes” and unzip the file.

Step 2. Run SSH Commands

After extracting the Magento package in the root directory, run the following commands one by one in the SSH console:

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy
php bin/magento cache:clean
php bin/magento indexer:reindex

The above commands will refresh the database schema, update all dependencies, and flush caches. When everything is finished, you can check the Magento 2 admin panel and frontend to make sure the upgrade went smoothly.

2. Magento 2 Upgrade via Composer

Upgrading Magento via composer is an ideal method for every Magento 2 user. To make this possible, please just follow 4 following steps:

Step 1: Turn on maintenance mode

You should put your store in maintenance mode while upgrading. To enable maintenance mode:

php bin/magento maintenance:enable

It will create a new file var/.maintenance.flag. If you cannot disable maintenance mode, you can remove this file [Remmember!]

Step 2: Upgrade to Magento 2

In this case, I will upgrade to Magento version 2.4.7. See the latest releases on Download page, Github releases

Step 2.1 Pull package

Using the following command on terminal/command-prompt firstly:

composer require magento/product-community-edition 2.4.7 --no-update
composer update

Replace product-community-edition with the specific Magento package you’re upgrading to.

You may be asked for a username and password like this:

authentication keys

To generate Public/Private Key pair please read this

Run: composer upgrade magento/composer-root-update-plugin

Step 2.2 Flush cache

Now time to remove cache and generation. Run the following command line at the root folder:

rm -rf var/cache/*
rm -rf var/page_cache/*
rm -rf var/generation/*

Notes:

  • You may install Memcached, Redis cache…, you should flush those caches manually.

Step 2.3 Run Upgrade Magento

Run upgrade module, database schema

php bin/magento setup:upgrade

Step 2.4 Run compile, reindex

You should run compile and reindex for better performance after upgrading.

php bin/magento setup:di:compile
php bin/magento indexer:reindex

Notes:

  • In Ubuntu/Debian Linux, when you meet permission issues, remember to insert sudo at the beginning of every command like sudo composer update.

Step 2.5 Disable maintenance mode

You have turned on maintenance mode in step 2, now you have to turn it off. Run the following command line to turn it off:

php bin/magento maintenance:disable

Step 3: Check the current Magento 2’s version

Next, you can check the Magento 2’s version by running the command.

php bin/magento --version

If the system shows the cache write permission error, please add the following command to give write permission to pub and var directories:

chmod -R 777 pub var

Step 3: Run System Upgrade

Finally, click the System Upgrade option to perform the Magento 2 version upgrade. Note that you may also be asked to upgrade the PHP to the latest version during the process.

Control theme and extension updates

Updating themes and extensions is important after upgrading your Magento 2 platform. It will ensure compatibility and prevent potential issues that affect your store’s appearance and functionality.

For those using a custom-made theme, contacting the developers and requesting an audit to ensure compatibility with the latest Magento 2 version is recommended.

Besides, it is necessary to have front-end monitoring to ensure no misaligned or missing content, as this can significantly damage your store’s visual integrity.

Common Magento Upgrade Issues and How to Fix

When upgrading Magento, you may encounter some common issues. Here are some of the most common issues and how to fix them:

Addressing Component Dependency Conflicts

Upgrading Magento may encounter component dependency conflicts, potentially arising from incorrect edits to the JSON composer file or compatibility issues with third-party extensions. Resolving these conflicts is crucial for a successful upgrade.

To solve this issue, you should follow these things:

  • Restore the JSON Composer File: Start by restoring the JSON composer file. Ensure that the file accurately reflects the necessary dependencies for the upgrade process.

  • Incompatibility with third-party modules: It is necessary to check for updates available for the problematic module. If updates are found, install the latest version of the module. But if there are no updates available, you can disable the problematic module.

Resolving The “Cannot Create the Directory” Error

Encountering the “Can’t Create Directory” error is a common issue that can happen when you update Magento 2. This error often arises due to permission issues with directories and files under Magento’s var subdirectory.

To address this error, run the command: “php bin/magento setup:di:compile” to ensure that the necessary directories and files have the correct permissions.

Fixing The “Cannot Allocate Memory” Error

Cannot Allocate Memory error is also one of the common issues that occurs when the system has exhausted its available memory or swapped space.

Here’s how to tackle it effectively:

  • Optimize Memory Usage: Review and optimize Magento’s memory usage. Identify any extensions or processes consuming excessive memory and make necessary adjustments.

  • Consider Server Upgrade: If memory constraints persist, consider upgrading the server’s RAM or your server plan to accommodate the additional memory requirements.

  • Check for Memory Leaks: Detect and fix any memory leaks in your Magento installation. Addressing these leaks can prevent the recurrence of the “Cannot Allocate Memory” error.
