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 8.0 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 8.0 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 8.0, you can upgrade to PHP 7.4.

View Standard Upgrade Steps

Automatic Updating

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

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.

For more information about updating, please refer to the Automatic Updater documentation.

Updates from Beta 1

If you upgraded to WHMCS v8.0 Beta 1, you may experience problems retrieving the latest version of the software via the Automatic Updater. If updating directly from v7.10.2 or earlier, this issue will not apply.

To use the Automatic Updater to update from WHMCS v8.0 Beta 1, you must first apply a hotfix. For more information, see our forums.

Release Notes

Users and Client Accounts

WHMCS now supports accounts and users in a new end-user login management system. Accounts own services for a given entity. A single user can then manage multiple accounts.

New Admin Area Look

Admin Area Blend theme enhancements bring an updated look and better performance to the Admin Area. We've also added improved support for mobile devices and tablets.

Deprecation and Removal Notices

Removed Legacy PHP Support

Product support for the legacy PHP 5.6, 7.0, and 7.1 environments is removed. To install or upgrade, you must run PHP 7.2 or higher.

Removed PHP Extensions Requirement

The IMAP extension is no longer required. The GD extension is no longer required for some features, but is still required for WHMCS as a whole.

Deprecated v4 Theme

The v4 theme for the Admin Area is deprecated. If no admin accounts currently use this theme, upgrading will delete it. If the theme is in use, it will remain available for selection. However, admins who are assigned to this theme will move to Blend when you upgrade.

Deprecated AutoAuth

AutoAuth was announced as deprecated in WHMCS version 7.10, including an option to enable or disable the feature. When you upgrade, the feature is disabled regardless of its previous value. We will remove AutoAuth in WHMCS version 8.1.

Removed Boxes and Modern Templates

The Boxes and Modern templates have been removed.

If products or groups use one of these, upgrading selects a new template that emulates the deprecated template. The system assigns the new template to everything that previously used the deprecated template. Newly-created child templates are based on the Standard template.

This upgrade will not touch custom themes.

Removed Modules

We have removed the,, GameCP, MediaCP, and Kayako LoginShare modules.

Removed Legacy Files

We have removed whois.php from the Client Area file set. The pipe directory was deprecated and has been removed. Use crons/pipe.php instead.
