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

On-Demand Renewals

WHMCS 8.8 introduces on-demand renewals, letting clients renew eligible services before WHMCS has generated their next invoice. You can configure on-demand renewals globally and per-product.

Hook Data Changes

To accomodate returning the data for on-demand renewals, a new renewalsByType array returns for the following shopping cart-related hook points:

  • PreCalculateCartTotals
  • AfterCalculateCartTotals
  • CartTotalAdjustment
  • ShoppingCartCheckoutOutput
  • ShoppingCartViewCartOutput
  • PreShoppingCartCheckout
  • OverrideOrderNumberGeneration

The renewals arrays for these hook points are deprecated and we plan to remove them in WHMCS 9.0. If your custom code uses any of the above hook points, update it to use the new data structure as soon as possible.
