Force a License Update

In some circumstances, you must force WHMCS to perform a license update. For example, you may need to do this after purchasing a new addon module.

Move WHMCS to a New Server

When you move your WHMCS installation from one server to another, you may need to perform additional steps like updating your license.

Move WHMCS to a New Subdomain

When you move your WHMCS installation from one subdomain to another on the same server, you may need to perform additional steps like updating your license.

Optimize Performance

As your database size increases, you may experience slower page loads and other speed-related issues. Optimizing your database and reducing unnecessary data can help WHMCS run faster.


Update the System URL

To ensure that your WHMCS installation can function, your system URL setting must be correct at all times.
