Upgrade Process

WHMCS 8.0 and above requires PHP 7.2 or later. WHMCS 8.0 introduced support for PHP 7.4, and WHMCS 8.6 introduced support for PHP 8.1.

Make certain that you update to a WHMCS version that supports your desired PHP version or higher before updating PHP.

The Automatic Updater only displays updates if you are running a PHP version that is compatible with that WHMCS version.
For example, if you are running PHP 7.1 or earlier, you must update to PHP 7.2 or later before updating to WHMCS 8.0 or higher.

Upgrade Instructions

Automatic Updating

If you are running WHMCS 7.0 or later, you can use the built-in Automatic Updater.

Go to Utilities > Update WHMCS to begin the process.

If the update was released recently, you may need to click Check for Updates before the update will be available.

Release Notes

OAuth2 Support for Microsoft® Services

If you use Microsoft's mail services, our newly-enhanced configuration options allow you to comply with Microsoft's upcoming requirements for OAuth2 authentication. This includes any Microsoft service that is compatible with Microsoft Azure® apps, like Hotmail®, Microsoft Outlook®, Microsoft 365®, and several others. OAuth2 offers enhanced security and replaces traditional password-based authentication.

You can configure Microsoft services for email importing at Configuration () > System Settings > Support Departments.
You can configure Microsoft services as your WHMCS installation's mail provider at Configuration () > System Settings > General Settings in the Mail tab.
