Upgrading from PHP 8.4

The smallest safe jump is to PHP 8.5, the closest version with active support. Upgrading several versions at once is common, but review the deprecations of every version in between.

Back up your files and database.
Check that your framework, CMS, theme and plugins support PHP 8.5. Test on a staging copy first.
Read the official migration guides on php.net for each version between 8.4 and 8.5.
Switch the PHP version in your hosting panel or install the new php-fpm package, then watch the error log.
Run the PHP Version Checker again to confirm.
