Magento, especially Magento 2, has long since been a synonym of robustness and extreme customizability. It is also frequently referred to as one of the enterprise’s strongest platforms. Having been around for quite a while, it has evolved to have one of the world’s largest fan and developer groups. According to Builtwith, Magento is ranked 3rd most popular in the top 10.000 sites in the Open Source category.
Generally, when you run an eCommerce store, it is always vital to upgrade your store to a more developed version to remain on top of the competition. Growing within each and every year, Magento 2 never stops to offer more and more robust versions, giving impetus for store owners to elevate their current Magento 2 store to another upgraded level. However, I bet some of you guys here are still skeptical about the most optimal way to conduct Magento 2 Upgrade.
Therefore, in this article, I will shed some light on two methods to conduct Magento 2 upgrade from 2.x to 2.y . In particular, this article will step-by-step detail the process of each method then compare one over another. We will, together, find out the best method for Magento 2 upgrade at the end of this article. Come along with us to see!
Methods for Magento 2 Upgrade
When it comes to Magento 2 Upgrade, store owners usually have two options to choose:
- Upgrade via Magento System Upgrade: Run system upgrade or upgrade with command-line
- Using automated Magento 2 Upgrade Service.
Then now let’s see what they are and how differently they are performed.
How to perform Magento 2 Upgrade via Magento System Upgrade
IMPORTANT: Before performing Magento 2 Upgrade via Magento System Upgrade, make sure you are TRULY confident with your technical and Magento knowledge, fixing code, PHP skills,… The reason is this process requires you to dive deep into Magento database structure. A lot of hard-to-fix errors may happen and they are related to inappropriate PHP setup, backup failure, file permissions,…etc.
Therefore, if you find yourself incapable of dealing with all these hardships on your own, straightforwardly skip to the automated Magento 2 upgrade solution with which you can perform the process seamlessly, without technical knowledge.
Anyway, let’s get started with the system upgrade!
A/ Run System Upgrade
System Upgrade prerequisites
Before starting, to avoid errors during your process, make sure you verify all below tasks:
- To set up a Magento file system owner and shared that owner’s group with the web server user group
- Your cron jobs are set up and running
- Set a value for DATA_CONVERTER_BATCH_SIZE
- File system permissions are set properly
After verifying the necessary tasks above, you need to complete all tasks discussed below:
Step 1: Select versions to upgrade
1.1. Choose which components to upgrade:
After you start System Upgrade, you’ll see the following page.

Then you have the following options in this page:
Item | Meaning |
Try Again, Next | Then hit Try Again to look for upgrades. |
Magento Core Components list | Shows available core component versions for upgrade. |
Other Components button | Allows you to look for upgrades for third-party components. |
Pagination | Lets you:
● To specify the number of items to display on a page. ● From left to right, move back one page, go to a specific page, or move forward one page. |
List of components | With each component:
● Set Upgrade to Yes to upgrade it. ● Set Upgrade to No to skip it |
1.2. Upgrade components
Click the core component version at Magento Core Components list to upgrade:

For each third-party component:
- If you want to upgrade, set Upgrade to Yes and choose the desired the version from the list.

- If you don’t want to upgrade it, set Upgrade to No

Step 2: Start readiness check
Click either Start Readiness Check or Next to proceed.

A successful readiness check message has been reported.

Frequently-Faced Errors
Error 1: Updater application is not available

Cause: This is due to an unavailable updater application
Solution: To resolve this issue, see if there is a <magento_root>/update
directory that contains files and subdirectories.
Error 2: Conflicting component dependencies
Cause: This message shows up if Composer cannot determine which components to install or update.
You are trying to update package(s) magento/module-sample-data to 1.0.0-beta We’ve detected conflicts with the following packages: – magento/sample-data version 0.74.0-beta15. Please try to update it to one of the following package versions: 0.74.0-beta16, 0.74.0-beta14, 0.74.0-beta13, 0.74.0-beta12, 0.74.0-beta11, 0.74.0-beta10, 0.74.0-beta9, 0.74.0-beta8, 0.74.0-beta7
Solution: Typically, component dependency conflicts arise when one manually edits the Magento 2 composer.json
file. The error can also comes from the third-party modules that depend on earlier Magento components than the ones you have installed.
In the above example, the installed package magento/sample-data version 0.74.0-beta15
cannot be upgraded to 1.0.0-beta
. However, 0.74.0-beta15 can be upgraded to 0.74.0-beta16
(or others).
Go edit composer.json
to make any of these changes and try the readiness check again.
Error 3: PHP version readiness check issues
- Unsupported PHP version
Cause: The check fails because you are using an unsupported PHP version.
Solution: To solve this issue, use one of the supported versions listed in 2.3.x System Requirements and 2.2.x System Requirements.
- PHP readiness check does not display

Cause: This happens due to incorrect cron job setup. The PHP readiness check doesn’t display the PHP version as the following figure shows.
Solution: This is a sign of incorrect cron job setup. For more information, see Set up cron jobs.
- Incorrect PHP version
Cause: Usually, this happens only to advanced users who have multiple PHP versions installed.
If the PHP version reported by the readiness check is incorrect, it’s the result of a mismatch of PHP versions between the PHP CLI and the web server plug-in.
Solution:
To solve the issue, try the following:
- Restart your web server or php-fm.
- Check the
$PATH
environment variable for multiple paths to PHP. - Use the
which php
command to locate the first PHP executable in your path; if it’s not correct, remove it or create a symlink to the correct PHP version. - Use a
phpinfo.php
page to collect more information. - Make sure you’re running a supported PHP version according to the system requirements:
- Set the same PHP settings for both the PHP command line and the PHP web server plug-in as discussed in PHP configuration options.
Step 3: Back up the file system and database
Follow these steps to back up:
3.1. Choose the checkbox of each item to back up and click Create Backup.

3.2. Wait until backups are done and continue with any of the following:

Frequently-Faced Errors
Error 1: Backup disabled
Backup functionality is disabled.
Backup functionality is currently disabled. Please use other means for backups.
Cause: If the Magento backup functionality does not start or displays the following message, you need to enable the feature prior to backing up.
Solution: Run the following CLI command:
bin/magento config:set system/backup/functionality_enabled 1
Error 2: Insufficient disk space
If the backup failed because of insufficient disk space, you should typically free up disk space by moving some files to another storage device or drive.
Error 3: Backup fails
If the backup fails or if all backup tests fail, it’s possible the Magento file system owner doesn’t have sufficient privileges and ownership of the Magento file system. For example, another user might own the files or the files might be read-only.
Solution: Pay particular attention to file system permissions and ownership of the <magento_root>/var
directory and subdirectories.
Step 4: Upgrade
To complete the upgrade, click Upgrade. If the upgrade is successful, a page similar to the following displays.


4.1. Clean the Magento cache
Run the command line:
bin/magento cache:clean
4.2. Manually clear directories
Once the upgrade is completed, manually clear var subdirectories by running the commands below:
rm -rf <Magento install dir>/var/cache/* rm -rf <Magento install dir>/var/page_cache/* rm -rf <Magento install dir>/generated/code/*
If you have varnish installed, after the upgrade completes, restart Varnish if you use it for page caching.
4.3. Restart Varnish
service varnish restart
Then access your storefront and verify if everything is working properly.
Frequently-Faced Errors
After you finish your upgrade, errors might display:
Error 1: On the main storefront page, the following error might display:
We’re sorry, an error has occurred while generating this email.

<your Magento install dir>/var/cache <your Magento install dir>/var/page_cache <your Magento install dir>/var/generation
B/ Upgrade via Command-line
Step 1: Turn on maintenance mode
To block any access during the process, it’s indispensable to turn on maintenance mode for your site.
Here’s how to do it:

- Enter the following command:
php <your Magento install dir>/bin/magento maintenance:enable
Step 2: Change to the directory in which you installed the Magento software.
For example: cd /var/www/html/magento2
Step 3: Run these following commands
composer require <product> <version> --no-update composer update
For example, to upgrade to Magento Open Source version 2.0.14, enter:
composer require magento/product-community-edition 2.0.14 --no-update composer update
Step 4: Enter your authentication keys.
Step 5: Manually clear var subdirectories
Run the following command lines:
rm -rf <Magento install dir>/var/cache/* rm -rf <Magento install dir>/var/page_cache/* rm -rf <Magento install dir>/var/generation/*
Step 6: Update the database schema and data

The following error might display: “We’re sorry, an error has occurred while generating this email”.
Please perform the following tasks:
- Reset file system ownership and permissions as a user with root privileges.
- Clear the following directories and try running these folowwing command lines again:
<your Magento install dir>/var/cache <your Magento install dir>/var/page_cache <your Magento install dir>/var/generation
After the upgrade, again check your Magento version with the following command:
php bin/magento —version
Frequently-Faced Errors
Error 1: There are no commands defined in the “setup” namespace on windows.
Solution: Mention setup_version
in your module.xml file. Your module.xml file should be like this:
<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd"> <module name="Vendor_Module" setup_version="1.0.0"/> </config>
You need to give full permission to both var and pub folders.
sudo chmod -R 777 var pub
Error 2: php bin/magento setup:upgrade not working
This is due to the permission issue.
Give permission and try again.
chmod u+x bin/magento
or
sudo chmod -R 0777 bin/magento
Error 3: Can’t create directory var/generation/Magento/
This is a permission problem, Magento is unable to write to your var directory. Follow the official documentation to setup your permissions properly.
What’s to conclude about Magento 2 System Upgrade Method?
This solution is made for DIYers, therefore, you’ll have no official support from Magento. In hours of need, there are still some decent Magento communities to reach out for help to solve arduous tech stuff and complex errors.
