Happy Addons is one of the recommended items if you are looking for an Elementor add-on. This add-on is available in two versions: free and paid/pro. You can download the free version of Happy Addons on the official plugin directory of WordPress. While for the pro version, you can download it from the official website of Happy Addons.
Just like other paid software, the pro version of Happy Addons requires a license key to be activated. If you have activated a Happy Addons Pro license on a certain domain and want to transfer the license to a different domain, Happy Addons allows you to do so.
How to transfer a Happy Addons Pro license to another domain
First off, login to the dashboard of the website where the Happy Addons Pro license is currently being activated and go to HappyAddons -> License.
Click the Deactivate License button to deactivate the license.
Visit the Happy Addons website and login with your account. Click the Download tab on the left sidebar to download the Happy Addons Pro file. Once the file is downloaded, go to the My License tab and click the arrow button to show your license key. Copy this license key.
Login to the dashboard of a new website where you want to transfer the Happy Addons Pro license to and install the Happy Addons Pro from the file you have just downloaded above. Activate it right away once installed. Once done, go to HappyAddons -> Activate License.
Paste the license key you have just copied and click the Activate License button.
