From WHMCS Documentation

When you move your WHMCS system, if the domain, IP address, or directory you use it in is changing, you must update your license.

Methods to Use

The method to use to do this depends on your license type:

Purchased Directly from WHMCS

If you purchased your license from us directly, you can reissue your license from our client area without any manual intervention from us.

To do this:

  1. Log in to the WHMCS Members Area.
  2. Go to Services > My Licenses.
  3. Select your license key.
  4. Click Reissue under the Management Actions tab.
  5. Visit your WHMCS installation in the new location. The system will save the new valid access details.

Purchased from Your Web Host

If you received your license from your hosting provider, you can't reissue your license from our client area. This is because the domain and IP address cannot change. Contact your hosting provider to have them update the license for use at the new location.

If you are moving to a different hosting provider, you cannot move your license key with you and you will require a new license key for use at the new location.

Moving WHMCS

To move WHMCS:

  1. Disable or remove the WHMCS cron jobs from the old server. This prevents automation from running and making changes.
  2. Create a backup of your database following these instructions.
  3. Make sure the new server meets the system requirements.
  4. Transfer the files to the new server.
  5. Restore the database via phpMyAdmin on the new server and make any changes to the database settings in configuration.php.
  6. Use the appropriate method above to reissue your license for the new location.
  7. In the WHMCS Admin Area, update the system URLs at Configuration () > System Settings > General Settings or, prior to WHMCS 8.0, Setup > General Settings.
  8. Check whether the system properly modified your cron jobs, payment gateway callbacks, and email forwarders.
  9. Update your custom directory locations.
  10. Update your storage locations.
  11. Delete the WHMCS files from the old location.

Licensing While Offline

Licensing continues to function when WHMCS is offline. WHMCS uses a local key licensing system with periodic remote verification checks. Once every seven days, your WHMCS system will contact our server to ensure it is being run in the correct location and that the license is still valid. Whether your WHMCS system is online is not dependant on our server being online during the time the local key is valid.

If our licensing server is unavailable on the day of your next verification check, the system will allow up to three days to make a connection. If, after this time, the system still can't verify your license with our licensing server, your WHMCS Admin Area will become inactive until WHMCS can contact our server again.

The WHMCS Client Area will always remain online, even if you have an invalid or expired license, to ensure your clients have uninterrupted access.
