After backup the data, you need to check the technical requirements to make sure that the software, supported databases, and supported web servers are eligible to migrate Joomla 3 to 4. In order to do that, let’s access Menu System -> System Information.

Update to Joomla 3.10 and Pre-Update Check

Update Joomla 3.9.x to Joomla 3.10

Besides checking the technical requirements, you also need to check which version of Joomla 3 your site is. If your site is in Joomla 3.9.x, it’s necessary for you to update it to Joomla 3.10 since it is a bridge version for you to migrate to Joomla 4 quickly. Please don’t update to Joomla 3.10 if you don’t have any intention to move your site to Joomla 4 version.

In order to update to Joomla 3.10 version, you simply open Components -> Joomla! Update -> Options in the admin dashboard.

Joomla! Update

After that, let’s set up the update channel to Joomla Next. Don’t forget to save & close it

Joomla Next

Now, all you need to do is press the Check for updates -> Install the Update button. There will be a message to show that your Joomla version update status is successful. And it is now in the 3.10 version.

Pre-update Check

Since Joomla 3.10 comes with the pre-update check, you can check whether the extensions and template you are using can be compatible with Joomla 4 or not. Thus, when utilizing this function, you can easily know which extension is not ready for Joomla 4. After that, you need to decide to update, remove or unpublish it. This step will ensure that you can upgrade Joomla 3 to Joomla 4 without any trouble during the upgrading process.

  • Database Schema Check

In order to check Database Schema, you need to access Extensions -> Manage -> Database.

In case there will be a message showing that the schema is not updated, simply click on the Fix button.

Fix Joomla Database

Next, let’s go to Components -> Joomla Updates -> Check for Updates -> Pre-Update Check.

  • Third-party Extensions Pre-update Check

Thanks to the Pre-update Check feature, it’s easy and effective for you to know which extensions are incompatible with Joomla 4. After that, you need to update/remove/unpublish the incompatible extension packages.

If you want to keep the extension on your site, let’s update its package so that it can be ready for Joomla 4. So, in Joomla 3.10 version, simply go to Extension Manager -> Update tab -> Find Updates.

In case you think the extension isn’t important for your site after updating to Joomla 4, you can unpublish or uninstall it. Let’s open Extension Manager -> Manage, then press the Search Tools button and choose Select Type -> Package.
