Upgrade Magento 2 to Magento 2.x.x via SSH
In this article, I will explain how to upgrade your Magento version from Magento 2.x.x to Magento 2.x.x using Command-Line Interface (CLI). Please keep in mind that this upgrade supports a fresh installation of Magento 2, so it is not recommended to apply this method on your live store. After the upgrade, you can migrate your data from old Magento 2 store to newly upgraded Magento 2.1 & 2.x store.
Step 1: Access Your Server via SSH
You need to connect your server via SSH.
Step 2: Navigate to the Magento 2 Root Directory
Once your SSH connection is up, you will need to move to your target application folder. In that application folder, you will find the public_html folder which is the root directory of Magento 2.
Step 3: Upgrade Commands
Please follow the same order and use the commands listed below:
composer require magento/product-community-edition 2.2.4 --no-update
Note: As 2.2.4 is the latest version, these numbers can be changed accordingly. You can also Upgrade Magento 2.x.x to 2.x.x using the same process. you just need to change the version 2.x.x.
If you are getting any error-related platform requirements then run the below command.
composer update --ignore-platform-reqs
Note: It will ask for repo.magento.com authentication keys. For more information, visit this link.
