Upgrading Joomla 3 to Joomla 4 is a multi-step process that requires careful planning and execution. Here is a general overview of the steps involved:
Before starting the upgrade process, it’s important to create a full backup of your website, including the database and all files. This will allow you to revert back to the previous version if something goes wrong during the upgrade.
Make sure your hosting environment meets the minimum requirements for Joomla 4. This includes the latest version of PHP and MySQL.
Ensure that all your third-party extensions are compatible with Joomla 4. If any extensions are not compatible, you will need to find alternative extensions or custom code to replace them.
Disable all third-party extensions before starting the upgrade process to prevent conflicts during the upgrade.
Update your PHP version to the latest version supported by Joomla 4 and update your MySQL database to the latest version.
Download the latest version of Joomla 4 from the official website.
Use Joomla’s built-in update feature to perform the upgrade. This will update your files and database to the latest version of Joomla 4.
After the upgrade is complete, re-enable any third-party extensions that were disabled before the upgrade.
Thoroughly test your website to make sure everything is working properly.
It’s important to note that upgrading Joomla 3 to Joomla 4 is not a straightforward process and may require additional steps depending on the specific configurations of your website. It is recommended to take the help of Joomla experts or developers if you are not well versed with the process.
