• What should I know about LiteSpeed licenses?

  You must have a valid license in order to use LiteSpeed Web Server. LiteSpeed Cache (required for the use of our cache plugins) is included free in all of our current licenses and our 2-CPU+ legacy licenses, and is available as an add-on for all other legacy licenses.

  Licensing is flexible. If your business changes and you require more or less power from your LiteSpeed Web Server, you can easily upgrade or downgrade your license. If you no longer wish to use LiteSpeed Web Server, you may transfer or release your license.

• Can I upgrade/downgrade licenses?

  Yes, but there are some guidelines.

  Leased:

  • You can upgrade or downgrade any leased license to any other Web Host or Site Owner leased license at any time.
  • You can upgrade a Free Starter license, but you cannot downgrade to one.
  • You cannot upgrade a leased license to an owned license. If you wish to switch to an owned license, you must wait until the end of the leased license billing cycle, and order a new owned license.

  Owned:

  • You can upgrade an owned license but it will not extend the update expiration date. It will only give you a higher license.
  • You must purchase the yearly addon, if you wish to extend the update expiration date.
  • You cannot downgrade any owned licenses.

  Invoicing:

  • Downgrades are effective immediately, and a prorated credit for the difference in price between the two licenses for the remainder of the current billing cycle will be posted to your account.
  • Upgrades will result in a new invoice with a prorated charge for the difference in price between the two licenses for the remainder of the current billing cycle. The upgrade is effective upon receipt of payment.
  • The next billing cycle's invoice will reflect your new full monthly/yearly price.

  If you have any special needs not covered by the above, please contact our license department via ticket.
