The developers at Joomla are working on a new release for Joomla. No specific date has been announced for the release of Joomla 4, but web developers and designers should keep in mind that it is coming.

This release will have a whole new look for the Administrative side of your Joomla site and will have a different default template called "Cassiopeia".

It is important that you keep up with the upgrades for your current Joomla site as it will make the migration to Joomla 4 go more smoothly.

Will my Protostar template work with Joomla 4?

Joomla 4 has a different framework and will use Bootstrap 4 instead of Bootstrap 2.

There could be issues with your old template working properly with the new version of Joomla.

We will be told more about how the migration process works when the migration upgrade is released.

Developers should keep this in mind before spending too much time on styling their current Joomla sites.

Other things to keep in mind is which Extensions your site relies on. The developers for your Extensions may not release a version that works with Joomla 4, it depends on whether the Extension works with the new Joomla 4 framework and how many people use the Extension. It may not be worth their time and energy to upgrade it.

Can I keep my site in Joomla 3?

Certainly, you can keep your site running in Joomla 3. Keep in mind that the developers of Joomla will no longer support it or upgrade it. There will be no future bug fixes or security updates. This may also hold true for your Extensions or Templates.

What will Joomla 4 look like?

You can download the Alpha version of Joomla 4 to install on a test site if you want to see some of the changes to Joomla.

Keep in mind that this version is not ready for live sites and that no Extensions or Templates are available for Joomla 4 at this time.

You will see a very different looking Administrative menu. Many of the familiar Joomla features are still there and the basic concepts of Categories, Articles and Menus still exist.  The Media Manager will be improved for Joomla 4 as well as SEO features.

The Cassiopeia template is quite different from the Protostar template. The Cassiopeia template uses Bootstrap 4 and SASS. SASS is a way to simplify stylesheets to use variables.

What should I do to get prepared for the migration from Joomla 3 to Joomla 4?

Keep up with Joomla 3 upgrades. The last Joomla 3.9+ upgrade will be necessary to use the migration version to Joomla 4.

Make note of what Extensions you have installed. The fewer Extensions, the fewer migration issues. Some more obscure or older Extensions may never be upgraded to work with Joomla 4, so be prepared to delete them from your site.

Consider using this migration / upgrade to revamp your website. You may want to give your web site a whole new look and or functionality. This will be the perfect time to rework your site.

What will migration to Joomla 4 entail?

It is highly suggested that you keep your live site as a Joomla 3 site and run the upgrade on a copy of your web site that is not available to the public. It can take some time to iron out any issues with templates and framework and styling issues. There may be glitches with extensions, PHP versions and other things. You don't want your live site to look bad or function incorrectly.

The first thing you will need to do is to list out all of the Extensions that your current site is using. Check to see that a Joomla 4 version of these Extensions is available. If there is not a Joomla 4 version available, you need to either remove that Extension or wait for a new version of the Extension to upgrade. Chances are that your Joomla 3 Extension will not function properly with Joomla 4.

You will need to duplicate the files and the database in order to do create a duplicate site for your upgrade. You will either need to move your site to a subdirectory on the host server or copy your site to a local compute with XAMPP or WAMP software installed. When you do this, the configuration.php file needs to be edited to point to the duplicated database with its new name.

You will need to upgrade your duplicate site to the latest version of Joomla 3 in order to run the migration version of the upgrade.

The Joomla 3 to Joomla 4 upgrade will be a migration. This means that it will need to change the core files to work with the new framework and software.
