Older versions of Joomla!

If your website is using an earlier version of Joomla! than 3.9 then we recommend that you use the Joomla! Update plugin to update it to the latest available release before switching.

3rd Party Extensions

Check whether any 3rd party extensions used by your website are compatible with a version of PHP before changing.

If your website uses a 3rd party extension that is not compatible with either PHP 7.4 or PHP 8 then use a different extension to avoid increased risk of your website being compromised.
