Upgrading Magento to a new version can be done in several ways, here is a general overview of the process:
- Back up your store: Before upgrading, it’s important to make a backup of your store’s files, database and media folder. This will allow you to restore your store in case something goes wrong during the upgrade process.
- Prepare for upgrade: Before upgrading, check the system requirements and make sure your server meets the new version’s requirements.
- Put the store in maintenance mode: To avoid any interruption during the upgrade process, put your store in maintenance mode by creating a maintenance.flag file in your root directory.
- Compare the current version with the new one: Compare the current version of your store with the new one, check the changelog to see the new features and changes.
- Upgrade the core code: You can upgrade the core code by either installing the new version over the old one or by using the Magento command-line tool.
- Upgrade the database: After upgrading the core code, you need to upgrade the database. You can do this by using the Magento command-line tool.
- Rebuild the indexes, flush the cache and remove the maintenance flag: After upgrading, rebuild the indexes, flush the cache and remove the maintenance flag to bring the store out of maintenance mode.
- Test your store: After upgrading, test your store to make sure everything is working correctly.
It’s important to note that this process will vary depending on the version of Magento you’re upgrading from and to. It’s recommended to consult the Magento documentation and the release notes for the specific version you’re upgrading to, and also consider hiring a professional for the task.
