Upgrade Process

WHMCS 8.0 and above requires PHP 7.2 or later. WHMCS 8.0 introduces support for PHP 7.4. Earlier versions of WHMCS do not support PHP 7.4.

You will only see the WHMCS 8 updates within the Automatic Updater if you are running on PHP 7.2 or later. If you are running PHP 7.1 or earlier, to update to WHMCS 8 via the Automatic Updater, you will first need to upgrade to PHP 7.2 or PHP 7.3, and then check for updates and perform the update.

Once you are running WHMCS 8, you can upgrade to PHP 7.4.
